“…The study of the problems of the flow phenomena through a rectangular microchannel has become more interesting in heat transfer engineering as well as in fluid mechanics [10][11][12][13][14][15][16]. A rectangular micro-channel with nine different kinds of baffle configurations, such as, plane baffles at a distance Q1…”

“…Hydro-thermal characteristics of turbulent air flow are governed by the following continuity (equation ( 1)), momentum (equation ( 2)) and energy (equation ( 3)) equations [10][11][12][13][14][15][16][17][18][19][20][21][22][23]: For analyzing the hydro-thermal phenomena, near the walls and far away from the walls, the AA" <model is suitable due to the presence of L D term, blending function. To predict the accurate results, this model is used to transform the inner region of boundary layer to the <model at a higher .…”

“…At a fixed Re, they demonstrated that the value of Nu becomes maximum in case of trapezoidal-triangular baffles. Similar types of work are available in the literature [14][15][16][17][18][19][20][21][22][23].…”

The objective of this work is to discuss the turbulent air hydro-thermal phenomena over a rectangular microchannel with different types of baffle (rectangular, triangular, and trapezoidal) mounted on both the walls of the microchannel. The finite volume method with the second order upwind scheme has been utilized to discretize the governing equations and to study the turbulent airflow characteristics; the SST k-turbulence model has been adopted. For nine different cases, the different characteristics of fluid flow phenomena and thermal behaviour with the variations in the Reynolds number ranging from [5,000-25,000] and for three different values of inter baffle spacing have been studied in this manuscript. Due to the presence of baffle, it is revealed that the vortex arises on the upper wall and the thermal phenomena enhances with the decrease in inter baffle spacing.

“…Over the last few years, thermal efficiency of a flow has become one of the major issues in various engineering and scientific fields such as air conditioners, room coolers, chemical reactors, etc [1][2][3][4][5][6][7]. There are many mechanisms available to increase heat exchange in fluid media.…”

The aim of this study is to investigate the heat transfer characteristics of turbulent airflow phenomena in a rectangular micro-channel in presence of two plane shaped (type-1) and diamond shaped (type-2) baffles which will help to develop various heat exchanger models. Finite volume method has been used to solve the governing equations and the FLUENT software has been employed to visualize the simulation results. For both the baffles, the profile of flow structure, normalized velocity profile, normalized friction factor and average Nusselt number have been investigated with the variations of Reynolds number ranges between [10,000-50,000]. In terms of fluid flow and heat transfer phenomena, it has been found that in the presence of diamond shaped baffles (type-2) are more convenient than plane shaped baffles.
