Characteristics of Natural Convection Flow and Heat Transfer of Parallelogramic Enclosure With an Inner Circular Cylinder Using Liquid Nanofluids

Abstract: Fluid flow and natural convection heat transfer in a parallelogram enclosure with an inner circular cylinder using Cu-water nanofluid are studied numerically. Dimensionless Navier-Stokes and energy equations are solved numerically using finite element method based two-dimensional flow and steady-state conditions. This study evaluates the effect of different concentrations of Cu-water nanofluids (0% to 6%) with different Rayleigh numbers 10 3 ≤ Ra ≤ 10 6 under isotherm wall temperatures. The effects of geometri… Show more

“…Besides that, they compared inside a rhombus enclosure under unsteady-state conditions. The natural convection occurred between the inner circular cylinder placed within a parallelogrammical enclosure containing nanofluid was investigated by Majdi et al (2019) . Effects on natural convection flow inside a heated triangular body situated within an air-filled circular cylindrical cavity with different physical parameters such as inclination angle, radius ratio as well as Rayleigh number examined numerically by Xu.et al (2009).…”

“…Further, Tiwari and Das (2007) examined two-sided lid-driven differentially heated square cavity filled with nanofluids model which different form conventional Buongiorno (2006) model and explained behavior of particle size, momentum/thermal diffusivity, and temperature. Some recent attempts to describe in this direction are Mustafa et al (2016); Hayat et al (2017); Animasaun et al (2019); Prasad et al (2018); Vaidya et al (2019aVaidya et al ( , 2019b; Majdi et al (2019);Puroshotaman et al(2019) and Amini et al (2020).…”

“…They have reached the conclusion that the inner triangular cylinder's inclination angle had no impacts on average Nusselt number when radius ratio remained unchanged. Other researchers researched the impact of the change of the internal body location vertically [27][28][29][30][31][32][33][34][35][36], horizontally [37]. Kim et al [27], Hussain and Hussein [28] researched numerically the natural transfer of heat convection between cylinder which is placed in square enclosure filled by air.…”

“…It is also obtained that at high Rayleigh numbers for a certain value of vertical location, there will be bifurcation from steady into transient conditions. Majdi et al [34] investigated utilizing the method of finite element on natural convection between cylinder placed in nanofluid parallelogramic enclosure under various vertical position. The influence of Rayleigh number, nanofluid loading, vertical location and inclination angle of enclosure on heat transfer and fluid flow were illustrated in full-details.…”
