-
(HEFAT, 2017)Active coolers for pharmaceutical transport require maintenance significantly and present risks with movable parts. Passive coolers on the other hand have less components and do not require chilling units on board ...
-
(HEFAT, 2017)The rain zone is one of the most important area in the wet cooling tower. It contains about 20% of the overall heat and mass transfer of the whole wet cooling tower. The air drag in the rain zone accounts for more than 50% ...
-
(HEFAT, 2017)Liquefied Natural Gas (LNG) is obtained by cooling natural gas below -161 °C. The liquefaction reduces volume of natural gas by about 600-fold. The reduction in the volume makes natural gas transportation economical over ...
-
(HEFAT, 2017)The demand for high thermal conductivity substrates with electrically insulating materials are increasing with the emerging markets in power electronics and mobile telecommunication device packages. Effective heat transfer ...
-
(HEFAT, 2017)The recent trend of increasing demand for rechargeable energy storage systems leads to the possibility of high power and energy electrical batteries. Especially for mobile applications, minimizing size and weight of the ...
-
(HEFAT, 2017)In the present study, the dynamics of sessile droplet coalescence driven by electro-capillary action (due to external electric field) is investigated numerically. An electro-hydrodynamic model based on finite volume method ...
-
(HEFAT, 2017)Enhanced tubes with internally helical fins have been extensively used in the large heat exchangers. This paper experimentally determined the single-phase friction factor and heat transfer coefficients in an internal ...
-
(HEFAT, 2017)We present numerical investigations on a thermal energy stor- age (TES) system using organic phase change materials (PCMs) of RT42 for energy recovery from a heat source. To enhance the heat transfer rate, five types ...
-
Design and performance of single loop pulsating heat pipe capable of working in horizontal position (HEFAT, 2017)Pulsating Heat Pipe (PHP) is a promising device for heat transfer and became popular in last two decades. Heat transfer in PHP is a combination of sensible and latent energy exchange. Interfacial processes like bubble ...
-
(HEFAT, 2017)In the present work we develop a mathematical model for a bubble immersed in a Maxwell fluid insonified by an ultrasonic field. As in previous works we wanted to see the effect of the viscoelasiticy in the overall behavior ...
-
(HEFAT, 2017)A theoretical investigation is carried out to investigate the 2D flow, heat and mass transfer of magneto hydrodynamic flow of Casson fluid over three different geometries. Cattaneo-Christov heat flux with transverse ...
-
(HEFAT, 2017)In order to increase the thermal efficiency, gas turbines are designed to operate at higher temperature, which requires a highly efficient cooling structure. The dimples and ribs are effective structures to enhance the ...
-
(HEFAT, 2017)The breakup model developed by Luo and Svendsen (1993) implemented into CFD modelling of gas-liquid two-phase flows assumes that the bubble shapes are spherical. The simulation results usually yield an unreliable ...
-
(HEFAT, 2017)The optimization of cooling hole geometry for combined impingement and effusion cooling of gas turbine combustors was investigated. The most common design is for there to be equal number of impingement and effusion holes. ...
-
(HEFAT, 2017)This study focuses on the influence of the internal flow condition on turbine blade showerhead region film cooling. The elliptical leading edge model has five rows of film cooling holes with 15 holes each at fixed ...
-
(HEFAT, 2017)Self entraining diffusers are mechanical devices which are used to entrain ambient (cold) air to mix with the exhaust (hot) gases. These devices are commonly used at the rear of the gas turbine engines with the aim of ...
-
(HEFAT, 2017)The paper reports on the development of a numerical model for the simulation of a liofilization process in a vial. The lactose and mannitol-water mixtures are used as the working medium in the vial. Experimental analysis ...
-
(HEFAT, 2017)The use of Small Gas Turbine to meet on-site small-scale energy demand offers a great opportunity for preliminary energy saving and reduction of pollutant and greenhouse emissions. The properly designed atomizer can ...
-
(HEFAT, 2017)Micro/nano-structured superhydrophobic surfaces can enhance dropwise condensation via coalescence-induced condensate jumping in well-tailored supersaturation conditions. In this paper we report our energy-based analysis ...
-
(HEFAT, 2017)Binary or ternary blends of hydroflourocarbons (HFCs) and hydrofluoroolefins (HFOs) are recently emerging as possible substitutes for the high GWP (Global Warming Potential) fluids currently employed in refrigeration and ...
