Sadia Rashid, Tasawar Hayat, Sumaira Qayyum, M. Ayub, Jinde Cao
Purpose
The purpose of this study is to study flow caused by rotating frame. Effects of Darcy–Forchheimer and porous medium are considered to study velocity field. Concentration field is discussed in presence of activation energy. Darcy–Forchheimer in a rotating frame is examined. Flow because of stretched sheet fills t...... hiện toàn bộ
Formulation and experiments with high‐order compact schemes for nonuniform gridsInternational Journal of Numerical Methods for Heat and Fluid Flow - Tập 8 Số 3 - Trang 288-303 - 1998
W.F.Spotz
Considers the extension of a new class of higher‐order compact methods to nonuniform grids and examines the effect of pollution that arises with differencing the associated metric coefficients. Numerical studies for the standard model convection diffusion equation in 1D and 2D are carried out to validate the convergence behaviour and demonstrate the high‐order accuracy.
Predictions of swirling flow in sudden‐expansion dump combustor with flameholder side‐inlet using two‐step combustion modelInternational Journal of Numerical Methods for Heat and Fluid Flow - Tập 9 Số 7 - Trang 764-787 - 1999
Shu‐HaoChuang, Chih‐ShengYang, Nein‐JouWu
The swirling flow of sudden‐expansion dump combustor with central V‐gutter flameholder and six side‐inlets is studied by employing the SIMPLE‐C algorithm and Jones‐Launder k‐ε two‐equation turbulent model. Both combustion models of one‐step with infinite chemical reaction rate and two‐step with finite chemical reaction rate of eddy‐breakup (EBU) model are used to solve the present problem....... hiện toàn bộ

Purpose
The purpose of this study is to investigate the coherent structures of pulsed opposing jets by large eddy simulation (LES) model and proper orthogonal decomposition (POD) snapshot method. Flow pulsation as an active flow control method is considered for the enhancement of transport phenomena in impinging jets. T...... hiện toàn bộ
FEM PREDICTIONS FOR TWO‐PHASE FLOW IN A VERTICAL PIPE WITHOUT THE USE OF ANY EXTERNAL CORRELATIONSInternational Journal of Numerical Methods for Heat and Fluid Flow - Tập 3 Số 6 - Trang 565-575 - 1993
K.V.PRASHANTH, K.N.SEETHARAMU
A mathematical model is developed for the description of the thermohydraulics of the two‐phase flow phenomenon in a vertical pipe. Using an additional momentum equation for the slip velocity, it is shown that the computation of slip and pressure drop from the model equations is possible without the use of any external correlations. The finite element method is used to solve the governing e...... hiện toàn bộ
