It describes the process flow diagram and different zones of a gasifier. Equations for reactions in each zone are provided. The document also includes specifications for the designed gasifier and cyclone separator. Simulation results at different temperatures are presented.
The document summarizes the design and fabrication of a 3-axis CNC precision router. The objectives were to efficiently design and fabricate a router with micron-level precision at an economical cost for small industries in Pakistan. Various analyses including mathematical modeling, FEMA, static and dynamic analyses were performed to optimize the design. A 16mm ball screw diameter was justified. The router was fabricated using A36 steel with bolts, nuts, and pins. NEMA 23 motors, drivers, and infrared sensors were integrated along with Raspberry Pi and C# software. The router can accommodate multiple 3D printing heads and has future potential for milling and improved precision.

This document outlines the design and development of a CNC milling machine. The objectives are to create an efficient and cost-effective CNC machine for Pakistani industries as imported machines increase costs. It describes the literature review, design of the driver circuitry, software design, PCB design, hardware and software interfacing, and final assembly and testing. Creo Parametric was used for CAD modeling and converting files to G-code. A software was written to simulate the milling machine based on the CAD model. The G-code is transferred to the microcontroller to operate the machine hardware. Graphical user interfaces were developed for the Android codeCAM software. Future recommendations include adding multiple tool posts, a clip-based work
1. Students designed and fabricated a dual purpose gas-fired geyser that heats water and purifies it through distillation.
2. The design uses a copper coil running steam to both heat water in an elliptical water bowl and distill water in a water container.
3. Testing showed the device can produce 2 liters of distilled water per hour during hot mode and 0.6 liters per hour during pilot mode.
This final year project presents the design, fabrication and testing of Tesla Bladeless Turbine for a 500 W hydropower system. One of the important components of Tesla turbine is the disc; its dimensions are determined from previously conducted research from Warren Rice, who mathematically modeled the flow between two co-rotating discs. Other scientists validated his results and published turbine performance plot, which can be used for further research. Using these results of the discs, the dimensions of the shaft were determined by considering a shaft under cyclic loading. Bearings were selected using analytical techniques and then the dimensions of the stator that is the outer cylinder were determined considering it as a thin walled cylinder. The nozzle slot in the outer cylinder was considered as an initial crack and stress analysis were performed to ensure safe operation. The design parameters and the processes adopted to calculate these parameters are shown in the report. Using these dimensions, a three dimensional CAD model of the turbine is generated using Solid works 2016, and modified to eliminate any problems in the shape and dimensions of individual parts. The parts were then manufactured and assembled in the innovation lab at FME GIKI.
Once the assembly is completed, the turbine was tested under different working conditions, at the fluid mechanics lab of FME GIKI. In the end, the performance of the turbine was compared with that of conventional hydro-powered turbines, to see how much it can compete with the already accomplished turbines, used in the industry.

The document describes the design and fabrication of a single-effect vapor absorption refrigeration system using LiBr-H2O and exhaust heat. The system was designed to (1) be environmentally friendly by using waste heat, (2) have low running costs, and (3) meet energy demands sustainably. A car was used as the environment where the cooling load was estimated. Components like the generator, condenser, evaporator, and absorber were modeled in ASPEN and tested experimentally using exhaust from an electric generator and LPG. The system was able to lower the chamber temperature by 4-5°C and had a COP of 0.0012-0.0013 without including heat input.
