Abstract
A new model is proposed to express heat and moisture transfer in a sand mold containing water. The calculated values of temperature, moisture content, and gas pressure by the proposed modeling coincide well with reported experimental values. Furthermore, it is shown that the likelihood of blow holes is greatly increased with decreasing sand particle diameter because escape of vapor to the atmosphere becomes more difficult at lower permeability.
