Abstract The finite element method is applied to incompressible and statistically steady confined turbulent swirling flows. A velocity–pressure formulation is employed. The momentum and continuity equations are solved using a segregated algorithm. Two turbulence models, namely the standard κ–ε model and the algebraic stress model, are considered. It is shown that the algebraic stress model leads to significantly more accurate results in swirling flows compared to the κ–ε model. A novel way of implementing ...

A finite element procedure is presented for the solution of the Navier-Stokes equations, adopting a segregated velocity-pressure formulation. The procedure is based on the derivation of an approximate pressure equation, which allows the uncoupling of pressure and velocity solutions. This equation is derived from the discretized continuity equation by considering the relationships established between velocity and pressure in the discretized momentum equations. The numerical performance of the proposed ...

A finite element solution of the radiative heat transfer in participating media is presented. The expensive direct numerical treatment of the integrodifferential equations of radiation is avoided by employing the moment method, which allows the derivation of an approximate local field equation for the radiation intensity. This makes the procedure convenient for use in combined-mode heat transfer problems, where the coupling of the radiation model with the iterative convective flow solution is required. ...

Incompressible turbulent flow past a circular cylinder is computationally investigated by a cascade of turbulence modelling strategies. Results are compared with experiments, by keeping the focus on the predictability of the drag coefficient. Two-Dimensional Reynolds Averaged Numerical Simulations (2D RANS) and Two-Dimensional Unsteady Reynolds Averaged Numerical Simulations (2D URANS) are performed for a wide range of Reynolds numbers, encompassing the critical regime. It is shown that the drag crisis ...

Steady-state Magnetohydrodynamic mixed convection heat and mass transfer in the presence of thermophoretic and transverse magnetic field over a vertical flat plate embedded in a conductive fluid-saturated porous medium is investigated. Variations of the wall temperature and concentration are taken into account. The non-linear governing equations of the boundary layer in non-dimensional form are discretised by the finite difference method. An excellent agreement of the results with the previously ...

Blood flow in human aorta and its major branches is analyzed by computational fluid dynamics, for physiologic and extracorporeal circulation, the latter being the main focus. Mainly, a steady-state analysis is applied corresponding to extracorporeal circulation conditions. For physiologic circulation, pulsatile flow is also investigated. Distensibility of aorta walls is neglected. Blood is modeled as Newtonian fluid. The SST model is employed for turbulence in all cases, for a coherent treatment ...

Design/methodology/approach Experiments have been performed and computations carried out for a water test rig, for a Reynolds number of 4,600 based on combustor inlet mean axial velocity and diameter. Two cases have been investigated, one low swirl and the other high swirl intensity. Measurements of time‐averaged velocity ...

Emissions of nitrogen oxides from coal combustion are a major environmental problem because they have been shown to contribute to the formation of acid rain and photochemical smog. Moderate and Intensive Low oxygen Dilution (MILD) combustion is a promising technology for decreasing pollutant emissions and improving combustion efficiency. A combination of air preheating and fuel dilution with combustion products of low oxygen concentration are the main features of this technique. In the MILD combustion ...

Thermal behaviours of parallel and counter flow micro-heat exchanger are investigated numerically, with emphasis on the role of wall resistance and thermal entry effects. The influence of different parameters, such as, thermal resistance (R), Knudsen number (Kn), effectiveness (ε) and Number of Transfer Units (NTU) are investigated. It is found that the temperature jump at the walls increases with increasing R and Kn. On the other hand, the NTU increases with decreasing R and Kn. Furthermore, for counter ...

Controversy on superiority of pulsatile versus non-pulsatile extracorporeal circulation in cardiac surgery still continues. Stroke as one of the major adverse events during cardiopulmonary bypass is, in the majority of cases, caused by mobilization of aortic arteriosclerotic plaques that is inducible by pathologically elevated wall shear stress values. The present study employs computational fluid dynamics to evaluate the aortic blood flow and wall shear stress profiles under the influence of antegrade ...

This paper evaluates a Eulerian-Eulerian modelling of the dispersed two-phase flow in pulverised coal combustion. In contrast to the commonly employed Eulerian-Lagrangian procedures, which treat the gas phase by a Eulerian and the particulate phase by a Lagrangian frame of reference, the presently investigated approach applies a Eulerian description to both phases. In our implementation, the model is further simplified assuming a mechanical and thermal equilibrium between the phases. For validation, ...
