Transport equations Mass and heat balances
2017 3 9 The transport equations for mass and heat are obtained from conservation laws of mass on one hand and energy on the other hand We consider a volume V xed in space and bounded by a surface V = Sand we write the balance between the change of mass or energy within V and the net uxes of mass or energy crossing the bounding surface S.
