(Elsevier, 2012-07)This paper presents a geometric optimisation of conjugate cooling channels in forced convection with internal heat generation. Two configurations were studied; circular channels and square channels. The configurations ...
-
(Elsevier, 2013-11)This paper presents a three-dimensional numerical study of steady, laminar, incompressible flow and forced convection heat transfer through a microchannel heat sink with micro pin fin inserts for both fixed and variable ...
-
(Elsevier, 2010-06)In this paper we use constructal theory to determine the configuration of two rows of pin–fins so that the total heat transfer rate is maximized. The heat transfer across the fins is by laminar forced convection bathed ...
-
(Elsevier, 2011)This work describes the effect of steady-state laminar forced convection on multiscale rotating cylinders in cross-flow. The objective was to numerically maximise the heat-transfer-rate-density from the multiscale cylinder ...
-
(Elsevier, 2012-10)This paper presents the development of the three-dimensional flow architecture of conjugate cooling channels in forced convection with internal heat generation within a solid. Two types of cross-section channel geometries ...
-
(Springer, 2012)Data obtained from heat transfer relations discretized with the finite element method were used in developing dimensionless correlations, which led to determining prediction equations for the average edge temperature of ...
-
(Springer, 2012-06)The present paper is dedicated to an experimental study of the effect of gravity forces during condensation of R134a in an 8.38 mm inner diameter smooth tube in inclined orientations. Flow pattern, heat transfer ...
-
(Elsevier, 2009)This paper presents an improved flow pattern map for predicting the heat transfer coefficients during condensation of R-134a inside a smooth horizontal tube. Experimental tests were conducted over the low-mass flux range ...
-
(Elsevier, 2012-04)This paper presents a three-dimensional geometric optimisation of cooling channels in forced convection of a vascularised material with the localised self-cooling property subjected to a heat flux. A square configuration was ...
-
(Elsevier, 2012-08)In this paper an analytical model was developed to minimize the thermal resistance of an air cooled porous matrix made up of solid spheres with internal heat generation. This was done under the assumption of local thermal ...
-
(Elsevier, 2013-12)In the research for this paper, a GA–PNN hybrid system was used for modelling the convective heat transfer characteristics and pressure drop of TiO2–water a nanofluid in a fully developed turbulent flow based on an ...
-
(Elsevier B.V., 2011-10)The small-scale open and direct solar thermal Brayton cycle with recuperator has several advantages, including low cost, low operation and maintenance costs and it is highly recommended. The main disadvantages of this cycle ...
-
(Elsevier, 2012)The Brayton cycle’s heat source can be obtained from solar energy instead of the combustion of fuel. The irreversibilities of the open and direct solar thermal Brayton cycle with recuperator are mainly due to heat transfer ...
-
(Elsevier, 2009)This paper presents a signal analysis method used for condensing refrigerants that results in a modification in the prediction method for heat transfer based on probabilistic time-fractional results. Development of an ...
-
(Elsevier, 2011-10)Tilting influences the flow patterns and thus the heat transfer and pressure drop during condensation in smooth tubes. However, few studies are available on diabatic two-phase flows in inclined tubes. The purpose of the ...
-
(ASHRAE, 2010-07)Design constraints and energy requirements have often led to heat exchangers operating outside of their design parameters. These parameters often involve the exchanger operating in the transition region of flow. Adiabatic ...
-
(Elsevier, 2012-08)Experimental data are reported for condensation of R134a in an 8.38 mm inner diameter smooth tube in inclined orientations with a mass flux of 200 kg/m2 s. Under these conditions, the flow is stratified and there is an ...
-
(Elsevier, 2010-01)This paper extends the design concept for generating multi-scale structures in forced convection for a finite-size flow system to a three-dimensional heat-generating plate with the objectives of maximising heat transfer ...
-
(Elsevier, 2010-11)Due to tube enhancements being used to achieve higher process efficiencies, heat exchangers are starting to operate in the transition region of flow. The paucity of data, however, has the implication that no correlation exists ...
-
(Elsevier, 2011)Due to efficiency demands, augmented tubes are often used in heat exchangers with the result that many heat exchangers operate in the transitional region of flow. Due to the paucity of data, however, no data exists for ...
