ArifArif New Member ArifArif Join Date: Apr 2014 Location: Potchefstroom South Africa Posts: 3 Rep Power: 12	Dear All I need your help on Passive scalar interactions Coefficient and the implementation of Passive scalar interaction. ��=��(��1��1−��2��2)�� • J is the mass flow rate. • k is the interaction coefficient set under the Phase Interaction node. • ρ1 is the density of the Lagrangian particle. • ρ2 is the density of the Eulerian fluid. • ϕ1 is the value of the passive scalar for the Lagrangian particle. • ϕ2is the value of the passive scalar for the Eulerian fluid. • Ap is the surface area of the particle. II am not sure how to calculate or determined k in the above equation.
