Heat Transfer

Heat transfer through fluids, solids, and fluid-solid interfaces is modeled by STORM.  When heat transfer is being solved, the energy conservation equation solver is activated.

In many flow problems, there are solid objects within the computational domain. Though fluid cannot penetrate the solid-fluid interface, heat can be transferred through the interface and conducted inside the solid objects. In this circumstance, mass and momentum equations are solved in the fluid side only, but the energy equation is applied to both the fluid and solid regions. Because the solid-fluid interface requires attention to ensure appropriate conservation of energy, conjugate heat transfer analysis was developed.

Conjugate Heat Transfer

At the solid-fluid interface the following two conditions need to be met:

where the subscripts f and s are for fluid and solid respectively, and subscript i indicates interface. The two conditions state that the heat flux and temperature across the fluid-solid interface are continuous.
