Engineering Projects

Thermodynamic Analysis of Supercritical Cycle

Involved in finding the thermal efficiency of the supercritical cycle and developing the computer code for calculating all the parameters.

Thermal efficiency of supercritical power plant has been calculated by varying the inlet pressure and temperature of steam turbine.

Thermal efficiency is carried out for open feed water heater, a closed feed water heater, and combination of both.

Developed computer code to analyze based on thermal efficiency.

Thermal efficiency is calculated for different number of feed water heaters and compared each other.

CFD Analysis of Economizer to optimize heat transfer

Designed Economizer in ANSYS

Designed Heat tube using ANSYS and sent it to CFD for analysis.

Obtain the optimized heat temperatures

Manufacturing of Steam Turbine Rotor Blade

Manufactured turbine blade on lathe machine.

Key Accomplishments:

Manufactured turbine rotor blade on Lathe machine, using the blue print.

Window Regulator Project

Took different functions of the regulator.

Using FMEA 4th edition developed S, O, D values and then calculated the RPN values.

Based upon the RPN values took the required actions to decrease the S, O, D values.

Optimal Design of Ball Bearing

Designed a mild steel groove ball bearing and subjected it to static analysis by application of different loads till it attains plastic deformation.

Key Accomplishments:

Designed a ball bearing with optimal conditions mentioned in journal using CATIA.

Stress analysis of the designed ball bearing is calculated using ANSYS.

The stress analysis test is done on the ball bearing using different loads.

Optimization of Efficiency of a Power Generation System.

Designed a power generation system using Rankine Cycle.

Increased the efficiency of the system by rise in the average temperature of working fluid entering the turbine.

Understeer gradient process.

Results of a constant radius turn-test performed on two vehicles are given.

Using the information, understeer behavior of two vehicles at various levels of lateral acceleration is simulated and is compared.

Stopping distance simulation.

Using given vehicle data, different slip conditions stopping distance is calculated using excel.

Brake Design and Problem Solving Project.

A brake drum crack problem was given in an application error.

New brake drum design parameters were calculated that can withstand operating conditions.
