| Name | Description |
|---|---|
| Delta T across the boundary layer is zero (infinite h.t.c.) | |
| Constant heat transfer coefficient | |
| Constant heat transfer coefficient - different grids for fluid and wall side | |
| Constant global thermal conductance (UA value) | |
| Flow-dependent h.t.c. gamma = gamma_nom*(w/wnom)^alpha | |
| Flow-dependent global thermal conductance UA = UAnom*(w/wnom)^alpha | |
| Dittus-Boelter heat transfer correlation | |
| Dittus-Boelter 1-phase, constant h.t.c. 2-phase | |
| Separate h.t.c.'s for each phase, each changing as (w/w_nom)^alpha |
