Week 8 - Simulation of a backward facing step in OpenFOAM

Backward Facing Flow: when flow enters the domain from inlet,after some time the flow reaches the step, because of expansion of flow channel, pressure gradient exists, it detaches and a recirculation zone is formed. A turbulent boundary layer encounters a sudden back step, causing flow separation. Later the flow eventually…

        Fender Design - Wheel Arc Challenge

        Objective:

        Solution: In the given Fender-Wheel assembly, at section C, D, E has lower clearance than clearance required. But in section D, E has negative clearance (means wheel is outer side to fender). Due to such reasons the given Fender- Wheel assembly was failed as per Europian Standards. links for 1.wheel-arc report https://drive.google.com/drive/folders/1sHDHfIpgEBfaklY-EA2f-25NQW3xMXyi?usp=sharing…

              UNDER BODY COATING and its Purposes

              Objective:

              Undercoating  is a thick resilient coating applied to the underbody or chassis of an automobile to protect against impact damage from small stones, which would rapidly chip ordinary paint, allowing rusting to begin.  It is also used to protect the parts like internal body panels,…

                  Objective:

                      Symmetry Boundary Condition: Generally we will encounter an analysis where you need more computer memory and/or CPU speed that you can obtain. Therefore you should get familiar with methods for using efficient modeling techniques. One method of efficiently using finite volume method(FVM) modeling is to exploit…

                    QUASI 1D SUBSONIC-SUPERSONIC NOZZLE: A quasi-one-dimensional flow is one in which all variables vary primarily along one direction,say x. A flow in a duct with slowly-varying area A(x) is the case of interest here. In practice this means that the slope of the duct walls is small. Also, the x-velocity component u dominates…
