The choice of turbulence model can have a strong impact on results for many
turbomachinery zones. Palliative corrections to them and also transition modeling can have …

There are numerous unsteady flow influences in turbomachinery. These can potentially
make a substantial total impact on efficiency, and hence the environment and operating …

Usually, a body conforming grid is being used for computing the flow around an arbitrary
body. This approach requires coordinate transformations and/or complex grid generation …

Embedded mesh, immersed body or fictitious domain techniques have been used for many
years as a way to discretize geometrically complex domains with structured grids. The use of …

The Interpolated Bounce-Back (IBB) method and Immersed Boundary (IB) method are
compared for fluid-solid boundary conditions in the Lattice Boltzmann Equation (LBE) in …

This article presents the evolutionary history of immersed boundary methods (IBMs), tracing
their origins to the very beginning of computational fluid dynamics in the late 1950s all the …

The objective of this paper is to assess the accuracy and efficiency of the immersed
boundary (IB) method to predict the wall pressure fluctuations in turbulent flows, where the …

This paper addresses the development of a method to simulate and analyze unsteady flows
of incompressible and inviscid fluids in rectangular channels. Mathematically, the flow …

Turbulent flow inside a dished bottom baffled stirred tank reactor (STR) with a 45° pitched
blade impeller is studied numerically and experimentally. Three different impeller rotational …

Improper mass conservation and spurious pressure fluctuations are considered as two
serious limitations of the immersed boundary method (IBM) for modeling flow over …
