Numerical analysis of refrigerant flow along non-adiabatic capillary tubes using a two-fluid model
(Pergamon-Elsevier B.V. Ltd, 2009-02-01)
This work presents a numerical model to simulate steady state refrigerant now along capillary tube-suction line heat exchangers. commonly used in small refrigeration systems. The flow along the straight and horizontal ...

A two-fluid model for refrigerant flow through adiabatic capillary tubes
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014-01-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The flow is divided in a single-phase region, where the refrigerant ...
A mathematical model for wave propagation in elastic tubes with inhomogeneities: Application to blood waves propagation
(Elsevier B.V., 2007-12-15)
We study the propagation of waves in an elastic tube filled with an inviscid fluid. We consider the case of inhomogeneity whose mechanical and geometrical properties vary in space. We deduce a system of equations of the ...
Estudo experimental do desempenho de uma nova geometria de tubos para evaporadores de túneis de congelamento
(Universidade do Vale do Rio dos Sinos, 2012-06)
This study presents an analysis of hydraulic performance of the air side for a new tube geometry of evaporators used in freezing tunnel. These evaporators are heat exchangers with finned tubes and air in cross flow. The ...

Experimental analysis of heat transfer in packed beds with air flow
(2004-07-21)
Heat-transfer studies were carried out in a packed bed of glass beads, cooled by the wall, through which air percolated. Tube-to-particle diameter ratios (D/dp) ranged from 1.8 to 55, while the air mass flux ranged from ...
