先进材料疑固实验室 Application:Zone melting Laboratory of Advanced Materials Solidification From the mass balance,we have: (CL*-Cs*)Adx+(Co-CL*)Adx ALdCL* (1) L is the length of the liquid zone,A is the cross-section area of the bar. Equation(1)can be simplified to get: (Co-Cs*)dx LdCL* (2) We know Cs*=kCL*,so we can change equation(2)into: k(Co-Cs*)dx LdCs* anced M (3) 上海充通大￥ SHANGHAI JIAO TONG UNIVERSITYApplication: Zone melting From the mass balance, we have: (CL* - CS*)Adx + (C0 – CL*) Adx = ALdCL * (1) L is the length of the liquid zone, A is the cross-section area of the bar. Equation (1) can be simplified to get: (C0 – CS*) dx = LdCL * (2) We know CS*=kCL*, so we can change equation (2) into: k(C0 – CS*) dx = LdCS * (3)
