[Description:]
|
|
|
|
This "force model" does not influence the particles or the fluid flow! Using the
|
|
particles' temperature a scalar field representing "particle-fluid heatflux" is
|
|
calculated. The solver then uses this source field in the scalar transport
|
|
equation for the temperature. The model for convective heat transfer is based on
|
|
Li and Mason (2000), A computational investigation of transient heat transfer in
|
|
pneumatic transport of granular particles, Pow.Tech 112
|
|
|
|
[Restrictions:]
|
|
|
|
Goes only with cfdemSolverScalar. The force model has to be the second (!!!)
|
|
model in the forces list.
