| 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 |
