Hello everyone. In CFD-DEM coupled with thermochemical sub-models for biomass gasifification: Validation and sensitivity analysis(Wang, 2020), the author gave the calculation procedure of particle-particle and particle-fluid-particle conductive heat transfer(2.4.2, 2.4.3). I wonder that how to enable these conductive heat transfer? Or they are activated by default?
For particle-particle heat conduction, provide K_S0(M) for each solid phase.
For the particle-fluid-particle conduction, provide DES_MIN_COND_DIST & FLPC.
If you don’t provide, their are default values available in the code.
If you want to further improve the heat conduction calculation due to the artificial softening, you should provide e_young_actual(M) & v_poisson_actual(M) for each solid phase, and also ew_young_actual & vw_poisson_actual for wall.
Here M represents each solid phase.
Thank you so much! May I get your e-mail for further discussion?
Please post your problem here, so other people who have the same issue can also see it. And there are other experts on this if I can’t help.
Dear Xu,
Now I am confused how to call temperature, liquid water and carbon contents in particle? Should I use T_s(IJK, M), DES_x_s(IJK, H2O) and DES_x_s(IJK, carbon), respectively?
The particle temperature should be DES_T_s(NP)
Moisture in the particle phase should be DES_X_s(NP, H2O) etc.
Here NP is the particle number, note that IJK usually refers as the Cell ID.
Very grateful for your help!
