Eutectic batch melting with constant

When K is a constant, the bulk partition coefficient becomes 

If Dq Pq, then dDjdF Oand D decreases as melting proceeds and if Dq Pq, then dDjdF 0 and D increases during melting (Fig. lb). In fact, the relationship Dq implies the preferential melting of the 

Equation (1.16) is the famous non-modal batch melting equation from Shaw (1970).
