図 1 に計算領域の概要と固液二相流の計算例を示す.固体壁に囲まれた正方形領域 で,上下の壁は温度一定 (下壁は高温,上壁は低温), 側壁は断熱とし,流体に対して はノンスリップ条件を課す.初期条件として,同一サイズの $N_{p}$ 個の円形粒子を図 1(a) のように $\sqrt{N_{r}}\cross\sqrt{N_{r}}$ で規則的に配置する.格子分割は $200\cross 200$ を基本とするが,小 さい粒子を扱う際には,粒子径と格子幅の比が 10 倍となるようさらに細かくする. 初期条

HEAT TRANSFER ANALYSIS ON ROTATING FLOW OF A SECOND-GRADE FLUID PAST A POROUS PLATE WITH VARIABLE SUCTIONT. HAYAT, ZAHEER ABBAS,

So, the aim of this study is to analyze, numerically, the combined effect of thermal radiation and viscous dissipation on steady MHD flow and heat transfer of an upper-convected

On the other hand, the magnitude of the cross-flow velocity increases with the increase in either suction pa- rameter or frequency parameter, while it increases near the

In particular, we show that the q-heat polynomials and the q-associated functions are closely related to the discrete q-Hermite I polynomials and the discrete q-Hermite II

The present paper presents an existence, uniqueness and stability result for a hyperbolic–elliptic model of two–phase reservoir flow.. Furthermore, a widely used operator

27 found that multiple solutions exist for a certain range of ratio of the shrinking velocity to the free stream velocity which again depends on the unsteadiness parameter for

A large amount of friction and heat transfer data, for different values of the dimensionless pitch and height with square, rectangular, trapezoidal and triangular shape ribs, has
