Suction / Injection Parameter S
Mathematical Modelling — Fluid Dynamics & Heat TransferContinuum mechanics; boundary-layer similarity theory
Symbol
SS > 0 is suction and S < 0 is injection through the porous wall, set by the wall-normal velocity v_w.
Also known as:S
Variable
Dimension I
Definition
What it is — and what it is not
- What it is
- S1The wall mass-transfer parameter.
- Attributes
- S2Positive S is suction (fluid withdrawn), negative S is injection (fluid added); it sets the wall value of f.
