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 ...
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 ...
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 ...
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 ...
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 ...
The three-dimensional revolving flow of a particle-fluid suspension
above a plane surface has been considered. The flow
represents an extension of the classical B¨ odewadt flow to a twofluid
problem. The governing ...
The thin liquid film near the contact line is important for
droplet evaporation on a heated surface, however, it remains a
challenge for modeling and simulation since it operates from
macroscale down to nanoscale. The ...
An irreversible finite-time thermodynamics models of a
two-stage AR (absorption refrigeration) system with variabletemperature
heat reservoirs is established, the ecological
function and the ECOP (ecological coefficient ...
The objective of this study is to investigate the behavior of
thermal walls as elements in low energy consumption buildings
and residences. The problem is formulated based on one
dimensional model and solved numerically ...
In this paper, we present an application of artificial neural network (ANN) analysis in the thermovision identification of the studied thermal fields. Precise thermal field identification plays an important role in ...
The paper deals with theoretical and experimental aspects of the application of the lumped capacitance model (LCM) for the study of heat transport in different materials. The patented construction of the measuring chamber ...
Volumetric direct solar receivers have been proposed in
Concentrated Solar Power (CSP) applications since they present
higher efficiencies than standard surface receivers do. Silicon
dioxide sand has been proposed as ...
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 ...
Buoyancy-driven magneto hydrodynamic flow in a
liquid-metal filled cylindrical enclosure is investigated by
numerical simulations, the finite volume method was applied
to solve the mass, momentum and energy equations. ...

We have obtained an extensive data set of heat transfer
coefficient (HTC) measurements in (R-218, C3F8)/(R-116, C2F6)
zeotropic refrigerant blends. A horizontal thin-wall tube with a
circular cross-section and diameter ...
This paper reviews the quenching of a moving metal sheet
with series of jets from a mold. Experiments were conducted on
various samples and the temperature on the back side of the plate
was measured using an infrared ...

The simulation of a LiBr-H2O absorber using a porous fiber
for the heat and mass transfer between the liquid solution and the
refrigerant vapour is considered. Heat and mass transfer
processes are modeled by means of ...
Ahlers, M.; Koch, M.; Lagel, B.; Klingel, S.; Schlehuber, D.; Gehrke, I.; Eloo, C.; Bart, H.-J.(HEFAT, 2017)
The manipulation of the water wetting properties of heat exchangers into dropwise condensation by the use of microstructured surfaces promises an enhanced heat transfer. In order to design a hydrophobic surface geometry, ...
Lately TES systems for thermal applications, such as space
and water heating, air-conditioning, cooling, etc. have received
much attention. In TES system, energy is stored by changing
the temperature of a storage medium ...
