A discontinuous-Galerkin-based immersed boundary method
(JOHN WILEY & SONS LTD, 2008)
A numerical method to approximate partial differential equations on meshes that do not conform to the domain boundaries is introduced. The proposed method is conceptually simple and free of user-defined parameters. Starting ...
Computations of the flow past a still sphere at moderate reynolds numbers using an immersed boundary method
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2009-10-01)
This paper presents an immersed boundary formulation for three-dimensional incompressible flows that uses the momentum equation to calculate the Lagrangian force field indirectly imposing the no-slip condition on solid ...

A high-order immersed interface method free of derivative jump conditions for Poisson equations on irregular domains
(2020-12-15)
Immersed Interface Methods (IIM) arise as a very effective tool to solve many interface problems encountered in fluid dynamics, mechanics and other related fields of study. Despite their versatility and potential, IIM-inspired ...
Effects of short-term immersion and brushing with different denture cleansers on the roughness, hardness, and color of two types of acrylic resin
(2015-01-01)
Purpose: To investigate the cumulative effects of brushing (B) or immersion (I), using different cleansing agents, on the surface roughness, hardness and color stability of a heat-polymerized denture resin, Lucitone 550 ...
An Improved Immersed-Boundary Algorithm for Fluid-Solid Interaction un Lattice-Boltzmann Simulations
(Planta Piloto de Ingeniería Química, 2013-08)
An improved algorithm combining the features of the lattice Boltzmann and the immersed-boundary methods is presented. Following previous formulations, the method represents a fluid con-strained by flexible boundaries by ...
A discontinuous-Galerkin-based immersed boundary method with non-homogeneous boundary conditions and its application to elasticity
(ELSEVIER SCIENCE SA, 2009)
We propose a discontinuous-Galerkin-based immersed boundary method for elasticity problems. The resulting numerical scheme does not require boundary fitting meshes and avoids boundary locking by switching the elements ...
EVALUATION OF AN IMMERSED BOUNDARY METHOD FOR SOLVING THE FLUID STRUCTURE INTERACTION PROBLEM IN REFRIGERATION COMPRESSOR VALVES
(Int Center Numerical Methods Engineering, 2014-01-01)
In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...

In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...
Simulation of the flow through automatic valves of hermetic compressors by the immersed boundary method approach
(2011-12-01)
The main goal of the present work is to verify the applicability of the Immersed Boundary Method together with the Virtual Physical Model to solve the flow through automatic valves of hermetic compressors. The valve was ...
