We have been using Internal Combustion (IC) engines for more than a century now. The engines we use today are much better in performance, efficiency and emit a lot lesser pollutants. There is still a lot more to improvise, and industries are working on new technologies to develop the best IC engine possible. In today's…

The quasi 1D subsonic-supersonic isentropic nozzle flow problem was solved using Macormack method. Both conservative and non-conservative forms of equations were solved using octave. The textbook referred for this problem is Anderson J.D. Jr., Computational Fluid Dynamics. For simplicity, all the initial conditions are…

In this project, the flow over a throttle valve inside an elbow was simulated. The throttle was kept fully open and flow was simulated for steady state case. Two simulation runs for different meshes were run and results are compared below. 1. Base Mesh of 2e-3 and no Grid Scaling A case with base mesh of 2e-3 was simulated.…

In the modern world, diesel engines are used more commonly in trucks, heavy-duty equipment, marine vehicles, and also as backup generators for electricity. It is a challenge to design engines which have a fewer environmental impact, and also good torque-power characteristics and efficiency.  In this project, the effect…
