Detailed Description

template<class Thermo, class OtherThermo>
class Foam::meltingEvaporationModels::Lee< Thermo, OtherThermo >

Mass transfer Lee model. Simple model driven by field value difference as:

$\‍[ \dot{m} = C \rho \alpha (T - T_{activate})/T_{activate} \‍]$

where C is a model constant.

if C > 0:

$\‍[ \dot{m} = C \rho \alpha (T - T_{activate})/T_{activate} \‍]$

for

$\‍[ T > T_{activate} \‍]$

and

$\‍[ mDot = 0.0 \‍]$

for

$\‍[ T < T_{activate} \‍]$

if C < 0:

$\‍[ \dot{m} = -C \rho \alpha (T_{activate} - T)/T_{activate} \‍]$

for

$\‍[ T < T_{activate} \‍]$

and

$\‍[ \dot{m} = 0.0 \‍]$

for

$\‍[ T > T_{activate} \‍]$
