The document presents a seminar on Tesla turbines. It discusses the construction of Tesla turbines which have a rotor with smooth discs and openings, and a stator casing. It explains the boundary layer concept and theory of operation, where the fluid adheres to the disc surfaces and transmits rotational force. The document covers applications in pico hydro systems, and advantages like simple design and ability to handle various fluids, though efficiencies may be lower than conventional turbines.

NSW Department of Education and Training 2000. 51 Wentworth Rd. Strathfield NSW 2135.
Revised 2003.
Nikola Tesla invented this bladeless turbine (patented 1913) originally, which uses boundary layer
effect to run and not impingement of fluid upon the blades as in conventional. There are number of discs
sequentially mounted on a shaft and the fluid is made to flow in a tangential direction with considerable
pressure onto the discs with the help of an efficient nozzle, then follows a spiral path towards the centre
and exits axially. The discs rotate due to the basic properties of the fluid – viscosity and adhesion, as
momentum is transferred via this forces and kinetic energy of fluid is converted into the rotational energy
of the shaft. Many researchers have studied this concept and given various improvements with proofs
basically into two ways – one suggesting modifying the design of various components involved while
others to change the parameters involved.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

4. INTRODUCTION
• Tesla turbine is a bladeless turbine.
• It was patented by Nikola Tesla in 1913.
• It is a radial type turbine.
• Also known as Prandtl layer turbine and
boundary layer turbine.
Dept. of Mechanical Engg. 4IESCE
6. CONSTRUCTION
There are mainly 2 parts in the turbine.
Rotor
• Consists of series of smooth discs mounted on
a shaft .
• Each disk is made with openings surrounding
the shaft.
• These openings act as exhaust ports through
which the fluid exits.
Dept. of Mechanical Engg. 6IESCE
7. Stator
• The rotor assembly is housed within a
cylindrical stator, or the stationary part of the
turbine.
• Each end of the stator contains a bearing for
the shaft.
• The stator also contains one or two inlets, into
which nozzles are inserted.
Dept. of Mechanical Engg. 7IESCE
8. • To make the turbine run, a high-pressure fluid
enters the nozzles at the stator inlets.
• The fluid passes between the rotor disks and
causes the rotor to spin.
• Eventually, the fluid exits through the exhaust
ports in the center of the turbine.
Dept. of Mechanical Engg. IESCE 8
9. BOUNDARY LAYER CONCEPT
• A layer of fluid developing in flows with very
high Reynolds Number, Re, that is with
relatively low viscosity as compared with
inertia forces.
• Observed when bodies are exposed to high
velocity air stream or when bodies are very
large and the air stream velocity is moderate.
Dept. of Mechanical Engg. 9IESCE
11. THEORY OF OPERATION
• As the fluid moves past each disk, adhesive
forces cause the fluid molecules just above
the metal surface to slow down and stick.
• The molecules just above those at the surface
slow down when they collide with the
molecules sticking to the surface.
• These molecules in turn slow down the flow
just above them.
Dept. of Mechanical Engg. 11IESCE
12. • The farther one moves away from the surface,
the fewer the collisions affected by the object
surface.
• At the same time, viscous forces cause the
molecules of the fluid to resist separation.
• This generates a pulling force that is
transmitted to the disk, causing the disk to
move in the direction of the fluid.
Dept. of Mechanical Engg. IESCE 12
15. EFFICIENCY OF TESLA TURBINES
• Tesla claimed a theoretical efficiency of the
order of 95%.
• Actual turbine efficiency is estimated to be
about 60%.
• Practical results seems to be lower than
conventional turbines.
Dept. of Mechanical Engg. 15IESCE
16. APPLICATIONS
• It can be converted into a pump, called Tesla
pump.
• As a multiple-disk centrifugal blood pump.
• Pico Hydro applications.
• Fluids with high viscosities, abrasives, solid
particles or two phase fluids.
• As a waste pump.
• As a wind turbine
Dept. of Mechanical Engg. 16IESCE
17. PICO HYDRO
• Harness the energy of flowing water at
capacities smaller than 5kW.
• Lowest generating cost.
• Low environmental impact.
• Displacement of large populations is not
required.
Dept. of Mechanical Engg. 17IESCE
18. TESLA TURBINE AND PICO HYDRO
• Simple components and design.
• Local setting manufacture lowers capital and
maintenance costs.
• Lesser risk of erosion of discs.
Dept. of Mechanical Engg. 18IESCE
19. ADVANTAGES
• Low production costs.
• Simpler design and manufacture.
• Can be used for a variety of fluids.
• Can be easily reversed into a pump.
Dept. of Mechanical Engg. 19IESCE
20. DISADVANTAGES
• Low torque.
• Proof of its efficiency compared to
conventional turbines is still questionable and
needs more research.
• Loss of energy due to friction at high speeds.
Dept. of Mechanical Engg. 20IESCE
21. CONCLUSION
• Not compatible for applications where
conventional machines are adequate.
• Should be considered in applications where
conventional methods are inadequate.
• Applications which need small shaft power,
highly viscous fluids or non-Newtonian fluids.
