    An important analysis for automotive applications is to simulate the thermal behavior of components during cold-start conditions. As the timescales involved in fluctuating fluid behavior often varies significantly from the timescales in solid thermal behavior, it is not efficient to run an implicitly coupled conjugate heat transfer simulation. Simcenter STAR-CCM+ provides a coupling strategy that permits distinct transient timescales for the solid and fluid components.

Setting Up the Models

Models define the primary variables of the simulation, including pressure, temperature, velocity, and what mathematical formulation is used to generate the solution. In this example, the flow is turbulent and compressible.

The Coupled Flow model is used together with the default K-Epsilon turbulence model. As there are two materials (air and aluminum) present, two regions are required for the analysis. Define two sets of continuum models, each appropriate to a different region. By default, Physics 1 2D and Physics 2 2D are automatically created when the mesh is converted to two-dimensional. Use these continua for the fluid and the solid.

Rename the continua:


Original Name	New Name
Physics 1 2D	Air
Physics 2 2D	Aluminum Alloy

For the physics continuum, Continua > Air, select the following models in order:


Group Box	Model
