...Paluru Sreedevi; P. Sudarsana Reddy; Ali Chamkha Purpose This study aims to investigate entropy generation in unsteady Buongiorno’s model nanofluid flow inside a square cavity under the combined effects of thermal radiation, chemical reaction and Cattaneo–Christov heat flux, with emphasis...

...Mauro Minervino; Renato Tognaccini Purpose This study aims to propose an aerodynamic force decomposition which, for the first time, allows for thrust/drag bookkeeping in two-dimensional viscous and unsteady flows. Lamb vector-based far-field methods are used at the scope, and the paper starts...

...Rahimah Jusoh; Roslinda Nazar; Ioan Pop Purpose The purpose of this study is to describe the unsteady three-dimensional magnetohydrodynamic stagnation point flow of nanofluids with heat generation/absorption. Design/methodology/approach The comprehensive numerical simulations in this study...

...A. Mahdy; Ali J. Chamkha Purpose The purpose of this paper is to address the thermo-physical impacts of unsteady magneto-hydrodynamic (MHD) boundary layer flow of non-Newtonian tangent hyperbolic nanofluid past a moving stretching wedge. To delineate the nanofluid, the boundary conditions...

...M.M. Rahman; Hakan F. Öztop; R. Saidur; A.G. Naim; Khaled S. Al-Salem; Talaat A. Ibrahim Purpose The purpose of this paper is to make a numerical analysis on unsteady analysis of natural convection heat and mass transfer to obtain flow field, temperature distribution, and concentration...

... between the jet exit plane and the flat plate. Design/methodology/approach Because of the unsteady nature of the problem a time-dependent computation is carried out using the detached eddy simulation turbulence model. The OVERFLOW 2 CFD code was used with a highly resolved grid and small time steps...

...Ioan Pop; Siti Suzilliana Putri Mohamed Isa; Norihan M. Arifin; Roslinda Nazar; Norfifah Bachok; Fadzilah M. Ali Purpose The purpose of this paper is to theoretically study the problem of the unsteady boundary layer flow past a permeable curved stretching/shrinking surface in the presence...

...Saeed Dinarvand; Reza Hosseini; Ioan Pop Purpose – The purpose of this paper is to do a comprehensive study on the unsteady general three-dimensional stagnation-point flow and heat transfer of a nanofluid by Buongiorno’s model. Design/methodology/approach – In this study, the convective...
