The present paper is devoted to study the flow of an incompressible viscous, electrically conducting fluid (blood) in a rigid inclined circular tube in the presence of transverse magnetic field. The blood is considered to be Newtonian fluid. The analytical expression for velocity profile and flow rate are obtained. The velocity profile and flow rate for various values of Hartmann number and inc...

A theoretical study is made of hypersonic flows over thin bodies subject to the combined effect of leading-edge bluntness^, boundary-layer displacement as well as surface incidence,, Within the scope of the boundary-layer theory and the hypersonic small-disturbance theorys an approach is developed based on a flow model consisting of three adjoining regionss an inner laminar boundary layerj an o...

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...

on the basis of the steady-state two-dimensional theory of thermoelasticity, stress field around various holes in infinite isotropic plate is discussed. the plate is subjected to uniform heat flux and thermal insulated condition along the hole boundary is assumed. by using the complex potential functions and by applying the conformal mapping and solving the integral equations, the effect of blu...

A new approach to comer detection is described which is based on the generalised Hough transform. The approach has the advantage that it can be used when objects have curved sides or blunt corners, as frequently happens with food products; in addition, it can be tuned for varying degrees of corner bluntness. The method is inherently sensitive: we have shown how it may be optimised for accuracy ...

The present numerical investigation focuses on the leading edge bluntness effects double-wedge with varied aft-wedge angles exposed to low enthalpy hypersonic free stream conditions. ratio in this study varies, ranging from R/L1 = 0 (sharp edge) 0.577 (maximum allowable bluntness), along angle varying between {\theta}2 450 and 600. Noticeably, even a small can completely change shock interactio...

Aerodynamic drag of fast-moving train has significant impact on its fuel consumption and design safety. To improve aerodynamic performance, the forces surfaces must be reduced. Train’s front-end nose boundless geometrical variations that can applied for improved performance. Three geometric characteristics were used in present research: A-pillar roundness, length controls shrinking, bluntness. ...

In this paper a method is presented for torsional analysis of non-homogeneous tubes with arbitrarily shaped cross-sections. A previously presented method based on Bredt’s theory is extended to achieve formulas for torsional analysis. Shear modulus varies through the thickness according to a power law distribution. To validate the accuracy of the presented formulas for angle of twist and shear s...
