Numerical simulations of Newtonian fluid flow through a suddenly contracted rectangular channel with two different types of baffle plates

Numerical Study of Air-Flow Phenomena Through a Baffled Rectangular Micro-Channel

“…1b), where two baffles are alternately mounted on the micro-channel walls. In this work, flow is assumed to be viscous, steady, incompressible, Newtonian and body forces, effect of viscous dissipation and the radiation of heat transfer have been neglected [29].…”

“…The present problem has been governed by the following continuity, momentum and energy equations [26][27][28][29][30][31][32][33][34][35][36][37].…”

“…The parameters, and µ have been taken from the works of Dermitini et al [27] and Saha et al [29]. Here, , , p, and denoted as the components of mean velocity along x i and x j directions, pressure, Reynolds stresses and thermal stresses respectively.…”

“…When, ≥ 10 4 , the value of Nu has been taken from the Dittus and Boelter correlation form [31], and the value of f0 taken from the Petukhov correlation form [32] when 3×10 3 ≤Re≤5×10 6 . Here, Re, ℎ , , and described as per Saha et al [29][30][31][32].…”

“…The current work is a modification and extension of the experimental research works performed by Demartini et al [27], numerical work of Saha et al [29] and Saha [30]. The work of Dermitini et al [27] does not provide any kind of variation in terms of different baffle configurations and does not include the heat transfer phenomena.…”
