m u channel tube single elliptic Introduction

Thermal performance criteria of elliptic tube bundle in ...

Based on the circular tube, the elliptic tube with zero angle of attack has a maximum area goodness factor for all values of axis ratio. A better area goodness factor can be obtained also with the elliptic tube having α = 30° and 150° when the axis ratio ranges from 0.5 to 0.66.

Unbiased Diffusion through a Linear Porous Media with ...

This work is devoted to the study of unbiased diffusion of point-like Brownian particles through channels with radial symmetry of varying cross-section and elliptic shape. The effective one-dimensional reduction is used with distinct forms of a position-dependent diffusion coefficient, , found in literature, to obtain expressions for (I) narrow escape times from a single open-ended tube, (II ...

Pressure Drop Coefficients for Elliptic and Circular ...

It may be observed from Figs. 8 and 9 and Table 2 that the elliptic tube with b / a = 0.65 has a better performance than the circular tube, for Re > 200, and also than the elliptic tube with b / a = 0.5, for Re £ 800. For Re ³ 1000, the elliptic tube with b /a = 0.5 is the one that possess the better performance. For Re > 1000, the pressure drag seems to predominate.
