“…The results show a similar behaviour of the heat transfer rate: for moderate rotational velocities at low Reynolds numbers the heat transfer rate is enhanced and there is an envelope of conditions (Reynolds number, rotation speed and power-law index) in which rotation has a negative effect on the heat transfer rate. Similar research includes the works of Gshwendtner [16], Mohanty et al [17], Oesterle et al [18], Ozerdem [19], Paramane and Sharma [20,21], Yan and…”

In this paper we investigate the thermal behaviour of an assembly of consecutive cylinders in a counter-rotating configuration cooled by natural convection with the objective of maximizing the heat transfer density rate (heat transfer rate per unit volume). A numerical model is used to solve the governing equations that describe the temperature and flow fields. The spacing between the consecutive cylinders is optimised for each flow regime (Rayleigh number) and cylinder rotation speed. It was found that the optimized spacing decreases as the Rayleigh number increases and the heat transfer density rate increases, for the optimized structure, as the cylinder rotation speed is increased. Results further shows that there is an increase in the heat transfer density rate of the rotating cylinders over stationary cylinders.

“…The authors of the paper [1] investigated numerically the effect of rotation rate on the flow and heat transfer across a rotating cylinder in the range 0 ≤ α ≤ 6 with Re number varying in the range 20-160. They concluded that the rotation can be used as a drag reduction and heat transfer suppression technique.…”

In this work, steady flow-field and heat transfer through a copper-water nanofluid around a rotating circular cylinder with a constant nondimensional rotation rate α varying from 0 to 5 was investigated for Reynolds numbers of 5-40. Furthermore, the range of nanoparticle volume fractions considered is 0-5%. The effect of volume fraction of nanoparticles on the fluid flow and heat transfer characteristics are carried out by using a finite-volume method based commercial computational fluid dynamics solver. The variation of the local and the average Nusselt numbers with Reynolds number, volume fractions, and rotation rate are presented for the range of conditions. The average Nusselt number is found to decrease with increasing value of the rotation rate for the fixed value of the Reynolds num- * Corresponding Author.
