“…They concluded that the rotation can be used as a drag reduction and heat transfer suppression technique. The suppression of von Karman street was also reported numerically in [2] for Reynolds numbers of 20-200 and rotation rate of 0-6 at Prandtl number (Pr) of 0.7. For steady regime, a well-organized numerical study was published in [3].…”

In this work, steady flow-field and heat transfer through a copper-water nanofluid around a rotating circular cylinder, dissipating uniform heat flux, with a constant non-dimensional rotation rate varying from 0 to 5 was investigated numerically using a finite-volume method for Reynolds numbers from the range 10-40. Furthermore, the range of nanoparticle volume fractions considered is 0-5%. 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 increase with increasing the nanoparticle volume fractions and decrease with increasing value of the rotation rate.

“…cells attached to the wall) is h Dt . The location of the outer boundary of the domain is expected to become more crucial for larger values of α [2,3]. In this study, following authors [3,4], the computational domain extends 150 times the diameter of the cylinder in all directions.…”

“…It should be noted that the time needed for the development of such subroutines is appreciably shorter than the time necessary for the development of an in-house code with similar capabilities owing to a large number of builtin functions. The chosen software package is universal and is suitable for simulating incompressible [17] and compressible [18] flows. However, for solving specific problems of aeromechanics, such as, e.g., simulation of the laminar-turbulent transition [19], the use of research codes based on high-order schemes with low dissipation is preferable.…”

Various issues of numerical simulation of supersonic gas flows with allowance for thermochemical nonequilibrium on the basis of fluid dynamic equations in the two-temperature approximation are discussed. The computational tool for modeling flows with thermochemical nonequilibrium is the commercial software package ANSYS Fluent with an additional userdefined open-code module. A comparative analysis of results obtained by various models of vibration-dissociation coupling in binary gas mixtures of nitrogen and oxygen is performed. Results of numerical simulations are compared with available experimental data.

“…The flow and heat transfer across the isothermal rotating cylinder with the rate of rotation in the range 0 ≤ α ≤ 6 and Reynolds number varying from 20-160 was carried by [3][4][5]. In the depth analysis, they revealed that the rotation can be used as a drag reduction and heat transfer suppression technique.…”

In this study a steady flow-field and heat transfer through a copper-water nanofluid around a circular cylinder, under the influence of both the standard thermal boundary conditions, i.e., uniform heat flux and constant wall temperature) was investigated numerically by using a finitevolume method for Reynolds numbers from the range 10-40. Furthermore, the range of nanoparticle volume fractions considered is 0-5%. The variation of the local and the average Nusselt numbers with Reynolds number, and volume fractions are presented for the range of conditions. The average Nusselt number is found to increase with increasing the nanoparticle volume fractions.
