Research Abstract 
In order to investigate the flow and the mass/heat transfer of solidfluid mixtures which have relatively large solid particles, we developed a new numerical method for the calculation of the flow and the mass/heat transfer of the solidfluid mixtures by using the lattice Boltzmann method. Next, we studied the characteristics of the flow and the mass/heat transfer of the solidfluid mixtures by the computations and the available experimental data. The results of this study are as follows. 1. A new numerical method for solidfluid mixture flows is developed by using the lattice Boltzmann method. 2. The calculated results of flows containing cylinder particles between parallel walls agree well with experiments. 3. The calculated results of flows containing sphere particles through a duct are compared with experimetns to verify the accuracy of the method. 4. The effect of the parameters (the ratio of particle diameter to duct hight, the volume fraction of particles, and the flow speed) on the mixture flow is clarified. 5. A new numerical method for mass/heat transfer of solidfluid mixtures is developed by using the lattice Boltzmann method for binary fluid mixture. 6. The mass transfer of the mixture of sphere particles and binary fluid is calculated and compared with experiments to verify the accuracy of the method. 7. The effect of the above parameters on mass/heat transfer is clarified. 7.パラメータ(粒子と管径との比、粒子の体積分率、および流速)を変化させた解析を行い、熱・物質移動機構と各パラメータとの関係を明らかにした。
