Experimental and numerical study on heat transfer enhancement in a channel with Z-shaped baffles

Thermal Hydraulic Performance in a Solar Air Heater Channel with Multi V-Type Perforated Baffles

“…Tall height tabulators, such as baffles, are generally used for increasing heat transfer rates due to the turbulence in the flow field. Typical shapes of baffles are transverse, angled shaped, V-shaped, perforated, and have multiple blockages that can be fitted and bent away from the heated wall to produce turbulence in the flow field that results in an improvement of Nu ave [6][7][8][9][10][11][12]. Furthermore, these baffles are modified to improve the thermo-hydraulic performance.…”

“…Khanoknaiyakarn [7] carried out an experimental study on Nu ave and f ave for V-shaped baffles using a broad heated wall with a large Wc/H value, and the effects of the baffles on Nu ave and f ave were reported. Sriromreun et al [8] experimentally determined the values of Nu and f for an air passage with a Z-type blockage. Bopche and Tandale [9] reported the turbulent flow in a rectangular passage rough with a U-pattern blockage.…”

CFD Analysis and Enhancement of Heat Transfer in Compact Shell and Tube Heat Exchanger by Using Camphor-Water

“…By increasing flat surface area of contact of fluid with its boundary than enhances the heat transfer rate. Parkpoom Sriromreun [4] by placing the zigzag shape baffles create co-rotating vortex flows having a great influence on the flow turbulence intensity which results in higher the heat transfer rate. Susheela Palanisami [5] an eco friendly mosquito repellent scattered with lemon grass oil.…”

Numerical Analysis of Thermal and Aerodynamic Fields in a Channel with Cascaded Baffles

“…Other similar works can be found in the literature, i.e, Fodor [10], Rábai and Vad [11], Hegedus et al [12], Füle and Hernádi [13], Goda and Bánhidi [14], Bidar et al [15], Khrabry et al [16], and Fenyvesi and Horváth [17]. The form geometry of the baffle is also a necessary structural parameter for the enhancement of the heat transfer phenomenon inside a channel, for example, ꞌLꞌ-shaped [18], discrete ꞌVꞌ and ꞌVꞌ-orifice [19], double ꞌVꞌ [20], diamond [21], helical [22], waisted triangular [23], and ꞌZꞌ-shaped [24].…”
