(HEFAT, 2017)Problem of falling film heat transfer is widely associated with many processes, such as shell side condensation and falling film evaporation in shell and tube heat exchangers. Efficient design of such heat exchangers can’t ...
-
(HEFAT, 2017)Methane and ethane are the main components in Liquefied natural gas and they belong to the group of natural refrigerants with high thermodynamic performances. In addition, methane and ethane are also the main components ...
-
(HEFAT, 2017)The use of surfaces with wettability gradient aims to cover the surface with drops of small size to allow a large heat exchange. Thus, the action of the wettability gradient on the surface of the substrate is twofold: ...
-
(HEFAT, 2017)This study focuses on a numerical simulation of phase change heat transfer between liquid and vapor. A numerical finite-volume approach was used to investigate the unsteady two-phase heat transfer problem. The initially ...
-
(HEFAT, 2017)When two bluff bodies is in close tandem, i.e, the distance between blocks D is less than half of the height of the body H, the flow field is very similar to that in the gap between tractor and trailer in a truck, and hence ...
-
(HEFAT, 2017)This work aims to perform the detailed experimental investigation of the flow field in labyrinth seal specimen using optical methods: LDA (Laser Doppler Anemometry) and schlieren visualization. Preliminary tests were ...
-
(HEFAT, 2017)It is well known that electrical-power generation is the key factor for advances in industry, agriculture, technology and the level of living. Also, strong power industry with diverse energy sources is very important ...
-
(HEFAT, 2017)Simulations were carried out to study the effect of free-stream turbulence (FST) on forced convection from a heated square cylinder in a cross-flow. The computations were performed using LES methodology with the dynamic ...
-
Potential of organic rankine cycles (orc) for waste heat recovery on an electric arc furnace (eaf) (HEFAT, 2017)The organic Rankine cycle (ORC) is a mature technology to convert low temperature waste heat to electricity. While several energy intensive industries could benefit from the integration of an ORC, their adoption rate is ...
-
(HEFAT, 2017)In traditional design and optimization of vehicle’s aerodynamic performance, there are few considering about engine compartment’s influence on vehicle's air resistance. In order to find out the engine compartment’s influence ...
-
(HEFAT, 2017)Traditionally the solar energy has used in southern countries, but it has used also in northern ones. Most popular kind of use of the solar energy in Latvia is solar collector for water heating. Traditionally flat-plate ...
-
(HEFAT, 2017)In the exploitation of geothermal energy, heat exchangers are essential to distribute heat to energy conversion systems (e.g. organic Rankine cycles) or district heating networks. The geothermal brine found in Belgium ...
-
(HEFAT, 2017)There are still some unknown aspects of nanofluids regarding simulations. Pool boiling flows are complicated in terms of numerical modelling and presence of particles can noticeably expand this complexity. Two-dimensional ...
-
(HEFAT, 2017)Low grade thermal energy with low temperatures of up to 150° C occurs e.g. as waste heat or waste steam in industry, or in in renewable energy systems such as solar thermal collectors or geothermal systems. The cost-effective ...
-
(HEFAT, 2017)Renewable energy sources, such as solar-thermal or geothermal heat, and low-/medium-grade industrial waste-heat can be converted into useful power and/or heating with a variety of technologies, including organic Rankine ...
-
(HEFAT, 2017)The transitional flow regime in the pressure drops of tube with twisted tape inserts is presented in this experimental investigation. This region of transition has not been previously identified for friction factors ...
-
(HEFAT, 2017)Numerous studies reveal that the heat transfer capability of thermal systems has been significantly enhanced with the use of nanofluids. On the other hand, the hazardous nature of the nanoparticles is evident. Recent ...
-
(HEFAT, 2017)In this experimental study, the Reynolds number limits of the transitional flow regime and friction factor characteristics were determined in the transitional flow regime of annuli. Isothermal and diabatic tests were ...
-
(HEFAT, 2017)A novel heat transfer fluid with bio-nanomaterial, which is environmentally safe, is prepared and its thermo-physical properties such as thermal conductivity and viscosity are measured. The bio-nanomaterial considered ...
-
(HEFAT, 2017)By considering quantum friction, heat resistance and heat leakage, this paper establishes a quantum Brayton heat pump model. The working substance is a two-level spin-1/2 system, and the cycle has four branches: two ...
