Finite volume methods (FVMs) constitute a popular class of methods for the numerical
simulation of fluid flows. Among the various components of these methods, the discretisation …

This study employs three-dimensional (3D) computational fluid dynamics (CFD) simulations
to investigate the influence of corrugations on direct contact membrane distillation (DCMD) …

We propose a family of gradient reconstruction schemes based on the solution of over-
determined systems by orthogonal or oblique projections. In the case of orthogonal …

Ultraviolet (UV) water disinfection method has emerged as an alternative to chemical
methods of disinfection. In typical UV photoreactors for water treatment, water flows in the …

This chapter is devoted to the description of finite volume method (FVM). FVM is a
discretization technique for partial differential equations, especially those that arise from …

The overarching goal of CFD is to compute solutions with low numerical error. For finite-
volume schemes, this error originates as error in the flux integral. For diffusion problems on …

Preconditioning of matrix systems obtained from an unstructured finite volume discretisation
of the incompressible NS equations are studied. The condition number is first estimated by …

A new discretisation scheme for the gradient operator, suitable for use in second-order
accurate Finite Volume Methods (FVMs), is proposed. The derivation of this scheme, which …

A finite volume method based unstructured grid is presented to solve the two dimensional
viscous and incompressible flow. The method is based on the pressure-correction concept …
