Hello,

You are correct. The _heat_transfer only affects the particle energy equation. The add__heat_transfer_rate provide a heat source to Fluent. 

The heat source is usually computed as S = Beta * (Tp - Tg), where Beta is the heat transfer coefficient, and T_p and T_g are the particle and fluid temperature, respectively. The explicit part will be obtained from Beta * Tp and implicit part is Beta itself since we don't know the fluid temperature of the cell in which the source term will be applied to. This information is still on Fluent's side. 

Best regards,

Lucas
