(HEFAT, 2016)This study is focused on numerical analysis of the thermal behavior within a scraped surface heat exchanger (SSHE) for threshold fluids (Bingham fluids). An innovative SSHE is considered which includes helical ribbon, ...
-
(HEFAT, 2016)Organic Rankine Cycles are often used in the exploitation of low-temperature heat sources. The relatively small temperature differential available to these projects makes them particularly vulnerable to changing ambient ...
-
(HEFAT, 2016)Sadatomi and Kawahara developed an efficient, i.e., energysaving- type, multi-fluid mixer, which can generate mists (or micro-bubbles) by introducing pressurized air (or water) alone because water (or air) as a source ...
-
(HEFAT, 2016)In this paper, the geometrical parameters of two heat exchangers in a typical commercial aircraft’s ECS system are designed using the Entropy Generation Minimization (EGM) design technique. The irreversibilities of all the ...
-
(HEFAT, 2016)The organic Rankine cycle (ORC) is a mature technology for converting low temperature heat to electricity. However before large scale adoption in waste heat recovery applications is attained companies need to be convinced ...
-
(HEFAT, 2016)We present an analytical solution of the convectionconduction problem, in laminar flow conditions in finite-length flat microchannels including slip/no-slip flows, effects of rarefaction, streamwise conduction and viscous ...
-
(HEFAT, 2016)In the present work, the unsteady and steady state heat transfer by natural convection in heat sinks, horizontally oriented, with flat and rectangular fins was studied. For that, the free and open source CFD software ...
-
(HEFAT, 2016)Wood-fired combined heat and power (CHP) plants are a proven technology for producing domestic, carbon-neutral heat and power in Nordic countries. Such plants are often of backpressure configuration, the district heat ...
-
Optimization of flue gas desulphurization absorber by means of computational fluid dynamics analysis (HEFAT, 2016)In the paper we present an optimization study/retrofit of the flue gas desulphurization (FGD) absorber focusing on the flow field in the desulphurization vessel and the performance of the rotary atomizer used there. The ...
-
(HEFAT, 2016)This paper reviews the available methods to study thermal applications with open-cell metal foam. For experimental research, the focus is on the repeatability of the experiments. Especially for open-cell metal foam, this ...
-
(HEFAT, 2016)This work aims at providing novel insights into the entrainment and energy exchange phenomena within a supersonic ejector. To this end, advanced analysis tools based on momentum and energy tubes (Meyers and Meneveau ...
-
(HEFAT, 2016)Earth tube system (ETS), which capitalizes on the high soil thermal inertia, is gaining popularity in recent years as an alternative to conserve energy for space cooling/heating in buildings. This paper presents a numerical ...
-
(HEFAT, 2016)Companies which produce aluminum alloy ingots seek a final product without structural defects. One crucial factor is the cooling during the semi continual casting process. In the beginning of the process, most cracks are ...
-
(HEFAT, 2016)Parallel micro or mini-channels are widely used in various devices of process and energy engineering including micro-reactors, compact heat exchangers and fuel cells. Nevertheless, the flow maldistribution due to the ...
-
(HEFAT, 2016)In this work, an innovative enhanced heat transfer tube (EHTT) is proposed, inserted with segmented conical-mesh frustums. The diameter of the bottom surface and the pitch between conical frustums were investigated while ...
-
(HEFAT, 2016)Heat exchangers having a bypass stream have wide ranging engineering applications such as heat sinks for electronics cooling. Due to their operating conditions, studies on the effect of the bypass region on the aero-thermal ...
-
(HEFAT, 2016)In the numerical study of heat sinks it is known from open literature that a sufficient amount of fluid domain should be added at each side of the heat sink. However, the question in this context is: what can be defined ...
-
(HEFAT, 2016)Large-eddy simulation (LES) is conducted to study the transition process of a separated boundary layer on a flat plate with an elliptical leading edge. A streamwise pressure distribution is imposed and the free stream ...
-
(HEFAT, 2016)The purpose of this work is to investigate and to understand the unsteady flow behavior in axial counter-rotating fan stage. 3D numerical simulations combined with experimental investigations were carried out, taking into ...
-
(HEFAT, 2016)With natural convective heat transfer from horizontal elements of relatively complex shape that have a uniform surface temperature it has been found that if a length scale based on the ratio of the element surface area ...
