Numerical analysis of heat transfer and fluid flow in a three-dimensional wavy-fin and tube heat exchanger

Numerical estimation of heat transfer characteristics for two-row plate-finned tube heat exchangers with experimental data

“…Their results show realizable k-ε model with non-equilibrium wall functions are used to obtain the closest results compared to the experimental data. Jang et al [16], Jang and Chen [17], Tutar and Akkoca [18], Sheu et al [19] and Xie et al [20] obtained fluid flow and heat transfer characteristics of the fin and tube heat exchanger under the assumption of laminar flow within the fins. It is found in [16][17][18][19][20] that the results obtained are also assumed to be independent of grid points.…”

It is found in [16][17][18][19][20] that the results obtained are also assumed to be independent of grid points. A comparison between the numerical and experimental temperature data is not made in [12,14,[16][17][18][19][20].…”

Effects of Geometric Parameters for Wavy Finned-Tube Heat Exchanger in Turbulent Flow: A CFD Modeling

“…In last decades, several efforts have been devoted to investigate the fundamentals and performance related issues in different experimental works (Kim, Youn et al 1996, Wang, Fu et al 1997, Wang 1999, Yan and Sheen 2000, Wang, Hwang et al 2002, Pirompugd, Wongwises et al 2006, Junqi, Jiangping et al 2007, Kim, Ham et al 2008, Wang, Liaw et al 2011, Dong, Chen et al 2012, Dong, Su et al 2013, Du, Feng et al 2013, Wu, Wu et al 2014. Also a number of numerical attempts have been accomplished in 2D/3D analysis (Jang and Chen 1997, Bhuiyan, Zaman et al 2010, Bhuiyan, Islam et al 2011, Glazar, Trp et al 2012, Gong, Min et al 2013, Bhuiyan, Amin et al 2014, Lin, Wang et al 2014. But most of the earlier works are limited to laminar to transitional ranges (Chu, He et al 2009, Bhuiyan, Zaman et al 2010, Bhuiyan, Islam et al 2011, He, Chu et al 2013, Bhuiyan, Amin et al 2014.…”

Numerical analysis on longitudinal location optimization of vortex generator in compact heat exchangers

“…Wan g et al [2,3] conducted an experimental study on pressure drop and heat transfer characteristics in fin and tube heat exchangers. Jang and Chen [4] investigated heat transfer and fluid flow in fin and tube heat exchanger using a numerical method. Afterward some other parameters, such as fin pitch or tube array, were investigated more precisely.…”
