In the description of define linearized mass transfer, the source term is processed as follows:<\/p>\n

<\/p>\n

\"\"<\/p>\n

<\/p>\n

I am curious about the expression of k1 and k2. If the source term is not proportional to afrom or ato, how to determine the expressions of k1 and k2. For exmple, the source term of Schnerr and Sauer cavitation model is proportional to a*(1-a). What the expression of m_dot is?<\/p>\n

<\/p>\n

For example, I have written a code.<\/p>\n

<\/p>\n

c_evap = 3.*F_evap*rho_l*rho_v\/(rho_mix*RB);<\/p>\n

<\/p>\n

m_dot = c_evap*sqrt((2\/3.0)*dp\/rho_l)*(1-vof_v);<\/p>\n

<\/p>\n

m_source = m_dot*vof_l;<\/p>\n

<\/p>\n

It didn’t work. As i removed the term “(1-vof_v)” in Line2, it was feasible, but I knew it was wrong.<\/p>\n

<\/p>\n

I hope someone can give some advices.<\/p>\n

<\/p>\n

Thanks!<\/p>\n
