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 ...
Computations of the flow past a still sphere at moderate reynolds numbers using an immersed boundary method
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014)
Numerical study of the atmospheric flow over a coastal cliff
(WILEY-BLACKWELL, 2011)
This work presents a numerical method suitable for the study of the development of internal boundary layers (IBL) and their characteristics for flows over various types of coastal cliffs. The IBL is an important meteorological ...
Numerical simulation of the flow through a compressor-valve model using an immersed-boundary method
(Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2016-01-01)
Hermetic reciprocating compressors are widely used in small- and medium-size refrigeration systems based on the vapor-compression cycle. One of the main parts of this type of compressor is the automatic valve system used ...
A simple and efficient direct forcing immersed boundary method combined with a high order compact scheme for simulating flows with moving rigid boundaries
(Pergamon-Elsevier Science Ltd, 2016-01)
A non-boundary conforming formulation for simulating complex flows with moving solid boundaries on fixed Cartesian grids is proposed. The direct forcing immersed boundary method (IBM) is implemented in a direct numerical ...
Identification of immersed obstacles via boundary measurements
(INSTITUTE OF PHYSICS, 2005)
An Eulerian Immersed Boundary Method for flow simulations over stationary and moving rigid bodies
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
The fluid flow over bodies with complex geometry has been the subject of research of many scientists and widely explored experimentally and numerically. The present study proposes an Eulerian Immersed Boundary Method for ...
Identification of immersed obstacles via boundary measurements
(IOP PUBLISHING LTD, 2005-10)
We study the following inverse problem: an inaccessible rigid body D is immersed in a viscous fluid, in Such a way that D plays the role of an obstacle around which the fluid is flowing in a greater bounded domain Q, and ...
Numerical solution and validation concerning a descriptive model of a simultaneous heat and mass transfer process
(Praise Worthy Prize, 2011-07)
This paper deals with the numerical solution of an initial moving boundary problem (IMBVP) arising from a simplified version of a free boundary problem (IFBVP) which was formulated in another paper, as a mathematical model ...
