In a previous paper the authors showed excellent prediction of filling patterns by the Hele-Shaw model for very thin charges. Experiments indicated the dramatic difference in flow patterns between thin and thick charges. In this paper, they relax some assumptions of that model, retaining all the viscous stress terms in the equation of motion, with the intent of finding the velocity profile and filling pattern of thick charges under both isothermal and nonisothermal conditions. The finite element method is used because of its capability for treating arbitrary shapes. The computed velocity profiles are given. The filling patterns from the three-dimensional isothermal and non-isothermal models are compared with that from the Hele-Shaw model. The differences are discussed and compared with experimental data.
