“…Smirnov (1978) obtained an asymptotic solution of the laminar rotating duct and gave a drag formula for this situation. Ovchinnikov and Rukolaine (1985) studied the development of laminar flow in a prismatic duct uniformly rotating about the (Wagner et al, 1991;Morris and Ghavami-Nasr, 1991;Han and Zhang, 1992;Han et al, 1993;Macfarlane and Joubert, 1998;Liou et al, 2001Liou et al, , 2003Martensson et al, 2002) and numerical studies based on the Reynolds-averaged Navier-Stokes (RANS) equations (Prakash and Zerkle, 1992;Tekriwal, 1994;Dutta et al, 1996;Hwang et al, 1998;Lin et al, 2001;Belhoucine et al, 2004) have been carried out on this topic, relatively few direct numerical simulations (DNS) or large eddy simulations (LES) results are available, especially results in which property variations are taken into account. Kristoffersen and Andersson did direct simulations of low Reynolds number turbulent flow in a rotating channel (Kristoffersen and Andersson, 1993).…”
