CFD simulations of vehicle aerodynamics and cooling systems (OpenFoam). Develop methodologies to improve the efficiency and effectiveness of our CFD

You could normalize the Q-criterion to help with this. But because this is so hard to decide (it's quite arbitary what this threshold is), the closely related lambda 2 criterion is often preferred over Q-criterion (where the threshold is 0). The Small Pool Fire tutorial in OpenFOAM but with higher resolution. This shows Iso-surfaces of Q criterion colored by velocity. 2019-05-05 · The Q-criterion can be used to identify vortex cores: \begin{align} Q &= \frac{1}{2} \left[ ( abla \cdot \boldsymbol{u})^2 – {\rm tr}( abla \boldsymbol{u}^2)\right] \\ TypeName ("Q") Runtime type information.

Open-source CFD: OpenFOAM is now a mature open-source CFD program with reliability matching that of commercial products. This page describes summary of utilities and dictionaries used in OpenFOAM such as blockMesh, snappyHexMesh, simpleFoam, pisoFoam, pimpleFoam, engineFoam Competence in CFD with OpenFOAM. This course has been designed over 6 months, drawing on 2000 hours OpenFOAM training experience. It enables competency: the confidence to repeatedly carry out CFD analysis to a defined standard. Confidence = not freezing at the keyboard.

Therefore, we need to fulfill the stability criterion Co < 1. Based on the fact that we set CoMax to 3, this is the reason why the simulation will blow up.
