Abstract The paper deals with the problem of enhancement cooling recycled water in industry. authors developed a new design hybrid tower fill pack consisting inclined-corrugated contact plates and tube radiator. flow during process flows inside radiator to avoid direct air, preventing biofouling process. In addition, external surface is modified by finning for heat transfer intensification. pur...
The strength of a corrugated container is usually determined and reported as crush strength under progressively increasing top-to-bottom compressive load. The test is performed in seconds in a controlled constant temperature and relative humidity environment. However, a dynamic strength test under controlled conditions cannot account for the reduction in load-carrying ability inherent in the ex...
The heat transfer characteristics of the working fluid passing through absorber a solar parabolic trough collector (SPTC) can be enhanced by creation turbulence effect. Therefore, novel idea was implemented introducing corrugated tube (CT) instead plain in collector. enhancement improved further use conical strip inserts inside SPTC. A receiver with pitch 8 mm and corrugation height 2 used thre...
The THz frequency range represents a true challenge for designers, fabrication technologies and characterization systems. So far, huge technological obstacles have prohibited any system realization different from laboratory one. Furthermore, most of the applications in the THz frequency range require a level of power not achievable by optoelectronic devices at room temperature or by solid-state...
A numerical investigation on Latent Heat Thermal Energy Storage System (LHTESS) based an aluminum foam totally filled with phase change material (PCM) is accomplished. The PCM used a pure paraffin wax melting over range of temperature and high latent heat fusion. LHTESS geometry under vertical shell tube. corrugated internal surface the hollow cylinder assumed at constant above temperature. oth...
We present a simple mechanical model for dynamic wetting phenomena. Metallic balls spread along a periodically corrugated surface simulating molecules of liquid advancing along a solid substrate. A vertical stack of balls mimics a liquid droplet. Stochastic motion of the balls, driven by mechanical vibration of the corrugated surface, induces diffusional motion. Simple theoretical estimates are...
To obtain the eigenmodes of the electromagnetic field at a periodically corrugated metamaterial we consider a theory of spoof plasmons propagating on metamaterial perforated with planar periodic grooves. We present the rigorous modeling and analysis of surface waves at the boundary of the corrugated metamaterial structure. Particularly, we pay special attention to the ways of controlling the pr...
