Week 3 Challenge : CFD meshing on Turbocharger

Aim: Perform CFD Volumetric Meshing of a Turbocharger. Theory:What is a Turbocharger?Turbocharger (often called a turbo) is a mechanical device which is powered by the exhaust gas flow of an internal combustion engine to increase its output power for a given engine displacement. The main components of a turbocharger include…

Aim: To perform Surface Meshing on a Pressure Valve. Theory: Setup: Importing geometry into the GUI of ANSA. Perform Geometry checks.  Geometry Cleanup:Single CONS are the main errors to be solved. Single CONS implies that there is a surface missing i.e.: a CONS is shared by only 1 surface instead of atleast 2 surfaces.So,…

Aim: To perform a parametric study on a gate valve by setting the opening from 10% to 80%.Theory: Valves are the devices used to direct, control or regulate the flow of a fluid by opening, closing or partially obstructing the flow passage. The valves classification can be summarized with the following picture:                           …

NASA came up with polynomials that can be used to evaluate thermodynamic properties such as Cp, H and S. They have also documented the co-efficients that are required to evaluate these polynomials for 1000+ species. So, according to problem statement we have to extract these coefficients for 53 species given in the attached…

Stalagmite Function: Stalagmite refers to an upward-growing natural structures formed due to mineral deposits that precipitates from the water dripping onto the floor of the cave.The stalagmite function when plotted on a 3d graph have the similar appearance and hence the name. The problem statement asks for optimization…
