Recent trends and progress in the immersed boundary method

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
The immersed boundary method is a methodology for dealing with boundary conditions at fluid–fluid and fluid–solid interfaces. The immersed boundary method has been attracting growing attention in the recent years due to its simplicity in mesh processing.

An immersed boundary-lattice Boltzmann method for thermal and thermo-solutal problems of Newtonian and non-Newtonian fluids

The Physics of Fluids, 2020
An immersed boundary-lattice Boltzmann method is introduced that can be employed for different thermal and thermo-solutal problems of Newtonian and non-Newtonian fluids. The general macroscopic and mesoscopic equations are presented and discussed.

Finite-Volume Discretizations and Immersed Boundaries [PDF]

, 2009
In this chapter, an accurate method, using a novel immersed-boundary approach, is presented for numerically solving linear, scalar convection problems. As is standard in immersed-boundary methods, moving bodies are embedded in a fixed Cartesian grid. The essence of the present method is that specific fluxes in the vicinity of a moving body are computed

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Cartesian Mesh Generation with Local Refinement for Immersed Boundary Approaches

Journal of Marine Science and Engineering, 2021
In this paper, an efficient and robust Cartesian Mesh Generation with Local Refinement for an Immersed Boundary Approach is proposed, whose key feature is the capability of high Reynolds number simulations by the use of wall function models, bypassing ...

cuIBM -- A GPU-accelerated Immersed Boundary Method [PDF]

, 2016
A projection-based immersed boundary method is dominated by sparse linear algebra routines. Using the open-source Cusp library, we observe a speedup (with respect to a single CPU core) which reflects the constraints of a bandwidth-dominated problem on ...

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Simulation and investigations on the vibro-acoustic behavior of cylindrical shells in ice-covered water

Results in Physics, 2019
Vibro-acoustic responses of cylindrical shells immersed in ice-covered water are typical acoustic-structure coupling problems. The dynamic model of the immersed cylindrical shell was established by Finite Element Method (FEM) to obtain the vibration ...
