Hello guys,
I am trying to develop my own solver. I am using openfoam version 8. I am wrote a code in twoPhaseMixtureThermo.C for calculating heat transfer coefficient. Code:
1.079 * (lambdaF_ / charLength_ ) * pow( (pow3(charLength_) * ifg_ * g_ * (thermo1_->rho() - thermo2_->rho()) )/ (lambdaF_ * mu_ * (Tsat_ - Tinf_) ) , 0.2 ) I found the issue of my code. (thermo1_->rho() - thermo2_->rho()) is causing error when I run test case(i.e damBreak problem). Code:
object of type N4Foam9rhoThermoE is not allocated So to remove that i declared a variable rhoE in twoPhaseMixtureThermo.H like this. tmp<volScalarField> rhoE = thermo1_->rho() - thermo2_->rho(); and used rhoE in above formula in twoPhaseMixtureThermo.C Code:
1.079 * (lambdaF_ / charLength_ ) * pow( (pow3(charLength_) * ifg_ * g_ * (rhoE) )/ (lambdaF_ * mu_ * (Tsat_ - Tinf_) ) , 0.2 ) Code:

Thanks in advance |
