AIM- File Parsing using NASA Thermodynamics data THEORY- File Parsing : File parsing is a method that helps us in decoding that data or in other words help us reading that data and use it in calculation of several parameters that defines the state of that environment. And analyse behaviour of different species changing…

Aim: The main objective of this project was to simulate and study the velocity, pressure, mass flow rate, and total cell count for all 3 base mesh sizes of the Rectangular Channel using CONVERGE Studio and observe the difference between the contours and line plots generated by running the 3 case study. Introduction Consider…

The case setup : The model was designed and imported to the converge studio and the bondary flagging was done. the simulation done was a time-based, steady-state simulation. Normal vectors were alligned in such a way that the flow was made to visualize inside the backward facing step body. An inlet pressure of…

Aim: The main objective of this project is to set up the case to perform simulation of steady-state flow over a Throttle valve when it is fully open and post-processing the result using ParaView. Introduction: The report contains a detailed description of the steady-state flow simulation over a Throttle valve using…

Aim: The major objective of this project was to perform a transient simulation for the flow of air over a throttle body when the throttle is moving at some angle in Converge Studio and post-process the results using ParaView. Introduction: The report contains a detailed description of the transient simulation over…

Shock Flow Boundary Conditions: For solving the steady state flow appropriate boundary conditions are needed. It is one of the required components of the mathematical model. On the other hand, for solving transient flow, appropriate initial condition is also required. Boundary conditions are generally three types.…
