A Pressure-Based Method for Unstructured Meshes

Large-eddy simulation of lean hydrogen–methane turbulent premixed flames in the methane-dominated regime

“…The inviscid flux at each cell face is evaluated using limited linear reconstruction [43] and Riemann-solver based flux functions [44,45], while the viscous flux is evaluated utilizing a hybrid average gradient-diamond path method [46]. A standard, explicit, two-stage, second-order-accurate, RungeKutta, time-marching scheme is used to integrate forward in time the non-linear, coupled-system of ordinary differential equations resulting from the finite-volume spatial discretization procedure.…”

Computation of Natural Convection in Channels With Pin Fins

“…The unstructured finite volume method described in Mathur and Murthy [14] is used. The calculation domain is divided to arbitrary unstructured polyhedral control volumes over which balances of mass, momentum and energy are written [15].…”

Numerical modelling of natural convection of oil inside distribution transformers

“…All this modularity and meshing quality is achieved through the use of a nonconformal grid type, splitting the meshed domain into different coupled zones. This meshing strategy is numerically possible due to the use of a code developed explicitly for unstructured meshes [21].…”

“…The pressure-velocity coupling is achieved through the use of the SIMPLE algorithm [23]. Diffusive terms of the equations are discretized using a second-order centred scheme, and the convective terms are discretized using a second-order upwind scheme [21]. A body force weighted scheme [24] is chosen in the discretization of pressure to deal with this buoyancy-driven flow.…”
