It is widely agreed that phase change materials (PCMs) are of high interest for sustainable energy future. Many of the applications require anti-leakage properties of PCM, that can be accomplished through PCM encapsulation. In this study, scalable and considerably simplified approach based on the microfluidics principles was successfully designed f...
Conference Paper
Synthesize routes of paraffin wax (PW) dopped by carbon nanostructures (fullerene C 60 and multi-wall carbon nanotube) as the phase change materials (PCM) with enhanced thermophysical properties have been discussed. Thermal conductivity of prepared composite PCMs in the solid and liquid states was measured. No any meaningful increase of thermal con...

A new composite heat transfer fluid consisting of tetralin and fullerene has been proposed for photovoltaic thermal hybrid solar harvesting. It features a unique absorption spectrum that is capable of sharply cutting off solar energy irradiated in the range of wavelength from 300 to 650 nm, making it a perfect candidate for simultaneous harvesting...

There is a scarcity of available data on boiling process in vertically oriented tube bundles in accessible sources. Lack of systematic studies is limiting further expansion of this highly efficient process of heat transfer into heat recovery field. In this paper boiling process of three triangular pitched and vertically oriented tubes has been stud...

The internal flow in corrugated tubes of different helical pitch, covering from the laminar to turbulent regime, was studied in order to characterize the three-dimensional flow and the influence of corrugation geometry on pressure drop and convective heat transfer. With water as working fluid and an imposed wall heat flux, ranging from around 4 to...

Impregnation of Phase Change Materials (PCMs) into a porous medium is a promising way to stabilize their shape and improve thermal conductivity, which are essential for thermal energy storage and thermal management of small-size applications, such as electronic devices or batteries. However, in these composites a general understanding of how leakag...

In the present study, the pool boiling process for the refrigerant R141b and its mixtures with Span 80 surfactant and TiO2 nanoparticles has been examined. The results for the heat transfer coefficient (HTC) were taken at various boiling pressures (0.2, 0.3, 0.4 MPa) in the range of the heat fluxes 5.8–56.4 kW m−2 and for the internal boiling chara...
Article
Recognizing the relevance of wettability in pool boiling heat transfer, few authors have reported significantly enhanced heat transfer coefficients using the so-called biphilic surfaces, i.e. hydrophilic surfaces with hydrophobic regions. However, the development of these patterns is still scarcely reported in the literature and many studies rely o...

The operating conditions of the pre-heater zone of an automotive vehicle waste heat recover heat exchanger occurs in, or close to, the transitional flow regime. For such an application the use of corrugated tubes in a cross flow tube heat exchanger is of particular interest. However, not much work has been done in the transitional flow regime in co...
