Abstract We present a moving control volume (CV) approach to computing hydrodynamic forces and torques on complex geometries. The method requires surface and volumetric integrals over a simple and regular Cartesian box that moves with an arbitrary velocity to enclose the body at all times. The moving box is aligned with Cartesian grid faces, which makes the integral evaluation straightforward in an immersed boundary (IB) framework. Discontinuous and noisy derivatives of velocity and pressure at…

A boundary thickening-based direct forcing immersed boundary method for fully resolved simulation of particle-laden flows
TLDR
A boundary thickening-based direct forcing (BTDF) immersed boundary (IB) method that can achieve a numerical accuracy comparable with other representative improved methods, such as multi-direct forcing (MDF), implicit velocity correction (IVC) and the reproducing kernel particle method (RKPM), while its computation cost remains much lower and nearly equivalent to the conventional DF scheme.

Fluid–Structure Interaction Study and Flowrate Prediction Past a Flexible Membrane Using Immersed Boundary Method and Artificial Neural Network Techniques
TLDR
Two-dimensional numerical simulation of flexible membrane fixed at two end points in a rectangular channel subjected to uniform fluid flow is carried out at low Reynolds number using a finite volume based IBM and an artificial neural network model is developed that successfully predicts flowrate in the channel for different membrane parameters.

TLDR
A fast and efficient, constraint-based self-propulsion formulation is employed to directly impose the preferred swimming kinematics, and the exploration of neuromechanical model for propulsion using fully resolved computational fluid dynamics becomes more tractable.
