Week 4 - CHT Analysis on Exhaust port

OBJECTIVE: 1. For the given model, check and solve all geometrical errors and Assign appropriate PIDs. Perform meshing with the suitable Target length and element Quality criteria. 2. Target lengths for the different parts of a model can be decided by your own. Finer mesh will give good results and will compromise…

Objective: For the given models: Engine, gearbox and transmission models, check for the geometrical errors and delete surfaces which are unwanted for Surface wrap as shown in the videos. After clearing geometry, Merge all 3 models and perform surface wrap. Target length for Wrap = 3 mm  AIM: As we are doing surface…

Objective: For the given model, check and solve all geometrical errors on half portion and Assign appropriate PIDs. Perform meshing with the given Target length and element Quality criteria. After meshing the half model, Do symmetry to the other side. Target lengths for the different parts of a model are as follow: Body…

Objective: For the given model, check for the geometrical errors to make appropriate volumes. Create and assign PIDs as shown in the video.

Note:- 1. Use methane-air-2step as a mixture material than methane-air. [It allows to add water in the fuel or air] 2. Use a one-step soot model to calculate the soot formation. 

What are some practical CFD models that have been based on the mathematical analysis of Rayleigh Taylor waves? In your own words, explain how these mathematical models have been adapted for CFD calculations. Perform the Rayleigh Taylor instability simulation for 2 different mesh sizes with the base mesh being 0.5 mm. Compare…
