Scavenging in Diesel Engines by tharun kumar.pptx
Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing it with fresh air. It is important for efficient combustion in engines. There are different types of scavenging methods based on the direction of airflow, including cross scavenging, loop scavenging, and uniflow scavenging. Uniflow scavenging provides the best scavenging efficiency but has more complex design requirements. Loop scavenging provides better scavenging than cross scavenging while remaining simpler than uniflow scavenging. The scavenging method selected depends on the engine application and design tradeoffs between performance, cost and complexity.

A review on techniques and modelling methodologies used for checking electrom...
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.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

PROTECTIVE DEVICES HANDLING OF FLUIDS AND MULTIPHASE SYSTEMS BY tharun kumar malapati.pptx
- 1. PROTECTIVE DEVICES HANDLING OF FLUIDS AND MULTIPHASE SYSTEMS Presented by M . Raju
- 2. Main View • FLUID • TYPES OF FLUIDS • MULTIPHASE • TYPES OF MULTIPHASES • HANDLING OF FLUIDS
- 3. FLUID • Fluid is a substance that continuously deforms with shear force. Examples:
- 4. TYPES OF FLUIDS • Steady fluid: It is the fluid whose density remains constant at each and every point while flowing. • Unsteady fluid: It is the fluid whose velocity differs between any two points while flowing. • Compressible fluid and incompressible fluids: These are classified based on the Mach Number. The incompressible fluid has Mach Number<0.3 and the compressible fluid has Mach Number between 0.3 and 1.
- 5. Multiphase • Two (or) more distinct phases flowing simultaneously in the mixture, and • Have some level of phase separation at a scale well above the molecular level. For example, Different-sized solid particles of the same material can be treated as different phases because each collection of particles with the same size will have a similar dynamic response to the flow field
- 6. TYPES OF MULTIPHASES • Solid • Semi-solid • Liquid • Gases
- 7. HANDLING OF FLUIDS • Liquid in relative motion is similar to the handling of fluids. 1) Motion along the Horizontal plane/track • tan 𝜃 = ℎ1−ℎ2 𝑙 • tan 𝜃 = ℎ1−ℎ2 𝑙 =(𝛼𝑋)/𝑔 • Where,𝛼𝑥=Accuration • g=gravity
- 8. 2)Motion along the incline plane: a)tan 𝜃 = ℎ1−ℎ2 𝑙 =(𝛼𝑥)/(𝑔 ± 𝛼𝑧) Where, 𝛼𝑥 = +𝑐𝑜𝑠𝜃 here, 𝛼𝑧 = − sin 𝜃
- 9. • Motion along the Vertical plane • 𝑝 = 𝑒𝑔ℎ[1 ± 𝛼 𝑍 𝑔 ] • The If container moving downwards with𝛼𝑧=g, • Then at point on the container , the pressure will be Zero(container falling freely)
