The enthalpy method is employed to numerical simulation of melting heat transfer in an enclosure with three discrete protruding heat sources on one of its vertical walls and all the other walls insulated.Numerical results have been compared with previous experimental results.It is found that discrete protruding heat sources have important influence on the shape of melting interface.

The numerical simulation of melting heat transfer in an enclosure with three discrete flush mounted heat sources on one of its vertical walls and all the other walls insulted is studied by means of the enthalpy method. Numerical results are compared with previous experimental and numerical ones.

Numerical computation to predict the pulverized-coal diffusion flame using Lagrangian treatment of the gas-solid flow and combustion is implemented. The authors analyse and discuss the gas-particle momemtum, mass and energy transfer processes. A modified scheme for existing computation model is proposed by the authors, which is effective in promoting two phase coupling process and can overcome divergency in computation for high pulverized-coal concentration combustion.
