Numerical models of reactive solute transport in groundwater are often solved using an approximate two-step approach that separates the transport and reaction processes. Even though the transport and reaction steps are split, using a novel formulation it is possible to pose the reaction step in...

A simple model is presented, which enables the calculation of ventilation in a commercial rose-growing greenhouse (greenhouse). The model represents the greenhouse as three vertically stacked horizontal segments and addresses the energy and vapor transfer among these segments and between them...
