Simcenter STAR-CCM+ to Simcenter STAR-CCM+ Coupling: Heat Transfer in a Chimney

This tutorial demonstrates the process for modeling conjugate heat transfer using Simcenter STAR-CCM+ to Simcenter STAR-CCM+ thermal co-simulation.

Using Simcenter STAR-CCM+ to Simcenter STAR-CCM+ co-simulation to solve multi-physics problems has the advantages that:
  • Regions can be developed independently.
  • Each case can be modeled with a relevant time-scale.
The diagram shows the case to be modeled. Hot exhaust gas enters a metal chimney with a temperature of 600 K and an average velocity of 0.2 m/s. The chimney has internal diameter of 0.4 m, a wall thickness of 10 mm and is made of T316 austenitic stainless steel. The external environment is assumed to be a perfect heat sink at a temperature of 283 K.

The tutorial is divided into three sections:
  1. In the first section, you create the solid model of the chimney.
  2. In the second section, you prepare the fluid model.
  3. In the third section, you couple both simulations to model the complete fluid-solid system.
