“…Those cylinders had been exposed to the top surface. Their results for the average Nusselt number and for inclination angle range from 0 to 180 ∘ were correlated as Nu (32) where W is the width ratio (width/height). Experimental study has been made on local and averaged natural convection heat transfer from inclined square cylinders in air at 30 ∘ ,45 ∘ , and 60 ∘ inclination angle to the horizontal by Ali [24].…”

Heat transfer by natural convection phenomenon has been studied by diverse researchers for several geometries and different boundary conditions. Different approaches were used such as numerical, analytical, and experimental approaches. In this chapter, we are going to review the most common published research on object shapes in natural convection heat transfer with their obtained numerical, semiempirical, and/or experimental correlations for the last two decades. These correlations are very important for engineering applications. This chapter will be stressed on cylinders in different orientations with cross sections such as circular, square, triangular, vertical, and horizontal coils and array of cylinders of different cross sections.

“…Rabari et al [12] investigated the effect of convection heat transfer on performance of waste heat thermoelectric generator. Many researchers [13][14][15] studied the nature convection, and many researchers focused on the forced convective heat transfer. Aydin et al [16] studied laminar forced convective slip flow in a micro-tube subject with an axially varying heat flux by using the finite volume method.…”

In this paper, a solution method for the temperature distribution of rectangular test specimen with a high-speed heat air-flow passing through is proposed based on the heat transfer theory and numerical calculation, and the feasibility of temperature prediction method is validated. Firstly, the partial differential equations to describe the average temperature in the section of the hot air-flow and the specimen are established and the solving method using MATLAB solver is proposed. Then, based on heat transfer conduction equation and the average temperature, the temperature distribution at different point in each section is calculated. The comparison between numerical computation and experiment shows that two results are in good agreement, which verifies the correctness of the presented prediction method of the temperature distribution of the specimen.
