Heat and Mass Transfer
1. Estimating the unknown heat flux on the wall of a heat exchanger internal tube using inverse method

M. Sh. Mazidi; M. Alizadeh; L. Nourpour; V. Shojaee Shal

Volume 5, Issue 2 , Winter and Spring 2016, , Pages 127-136


  In the design of heat exchangers, it is necessary to determine the heat transfer rate between hot and cold fluids in order to calculate the overall heat transfer coefficient and the heat exchanger efficiency. Heat transfer rate can be determined by inverse methods. In this study, the unknown space-time ...  Read More

2. Generalized solution of functionally graded hollow cylinder under torsional load

Y. Bayat; M. Alizadeh; A. Bayat

Volume 2, Issue 2 , Winter and Spring 2013, , Pages 23-32


  In this paper, a general solution for torsion of hollow cylinders made of functionally graded materials (FGM) was investigated. The problem was formulated in terms of Prandtl’s stress and, in general, the shear stress and angle of twist were derived. Variations in the material properties such as ...  Read More
