Phase-space advection mass and heat transfer

2 Phase-space advection mass and heat transfer 

In general, continuity statements are written in terms of particle mass ( j = Mp), from which all the other expressions are derived. The rate of change of particle mass due to the exchange of molecules with the fluid phase is usually written as 

Likewise, in the case of heat exchange between phases, continuous changes for the internal coordinates are induced. If, for example, one of the internal coordinates is the temperature of the particle, Tp, the rate of change of particle enthalpy can be calculated as
