Situation 3:No diffusion in the solid,Limited 先进材料疑固实验室diffusion in the liquid,no convection.. Laboratory of Advanced Materials Solidification We have (1-k) = D(1-k) a kR ⊕ Then kR = DL So kR C=C[1-(1-k)e元] Du kR Is the characteristic distance of initial transit state where the solute distribution reaches a steady state. ced 上浒充通大 SHANGHAI JIAO TONG UNIVERSITYWe have Then So Situation 3: No diffusion in the solid, Limited diffusion in the liquid, no convection.
