In this work, a novel design of real scale Scraped Surface Heat Exchanger (SSHE) for solar LTES has been developed and experimentally tested. The main issue in PCM heat exchangers is the growth solid layer at transfer walls during latent energy extraction/discharging, that lowers transfer. removal solidified through scraping increases rate with nearly constant flux. Those characteristics make it suitable domestic hot water generation. Discharging tests have performed no modes (SM nSM)....
Most post-cardiotomy (PC) extracorporeal membrane oxygenation (ECMO) runs last less than 7 days. Studies on the outcomes of longer have provided conflicting results. This study investigates patient characteristics and short- long-term in relation to PC ECMO duration, with a focus prolonged (> d) ECMO.
In this work, a parametric study of Scraped Surface Heat Exchanger (SSHE) for solar Latent Thermal Energy Storage (LTES) has been conducted. The primary challenge in Phase Change Material (PCM) heat exchangers is the formation solid layer along transfer surfaces during latent energy release phase. This reduction rate resolved through scraping solidified PCM, making SSHE systems suitable domestic hot water generation. Experiments have performed to evaluate influence various operational...
Data from early in vivo experiments demonstrated that the child-size Jarvik heart was capable of providing partial to nearly complete circulatory support with acceptable adverse effects on blood. However, bearing thrombosis responsible for device malfunction most cases. To overcome this problem, original pin bearings were replaced novel conical bearings. This study evaluated chronic performance modified pediatric setting. Six juvenile sheep implanted heart. Cardiac and pump output measured...
The main pipes in water distribution systems have, many cases, an excess of static pressure. This pressure is usually dissipated by means intermediate reservoirs, pressure-reducing valves or any other device that produces the required energy loss with aim to adjust level demand pattern system. hydraulic can be used directly drive a mechanical system generate electric power. In this type recovery systems, available power lower than 100 kW (micro-hydro). range, utilization conventional...
The long-term stability of a Phase Change Material (PCM) is key point for its selection in energy storage devices. This work studies the suitability commercial paraffin wax an active scraped surface heat exchanger solar purposes. In these devices, continuous scraping inner walls during solidification removes PCM and increases released heat. Hence, affected by high level shear stress. order to study potential degradation paraffin, novel accelerated procedure has been designed obtaining...
A 156MW steam cycle power plant has been chosen as a case study. Two repowering scenarios have utilized for this case. Thermodynamics code supplied combined and STIG compare with each others. The exergy exergoeconomic analysis method was applied in order to evaluate the proposed repowered plant. Also; computer developed analysis. It is anticipated that results provide insights useful designers into relations between thermodynamic losses capital costs; it also helps demonstrate merits of...
This work presents an experimental study of the thermal-hydraulic characteristics in a flat-plate solar collector with two different geometries helical coil inserts. Isothermal pressure drop tests are conducted horizontal tube using water as working fluid to obtain fully developed Fanning friction factor for range Reynolds number Re = 80–8,000. Heat transfer performed loop mixture propylene-glycol and at 30 wt%, covering ranges Pr 16–28 140–600. A significant decrease temperature absorber is...
A numerical investigation of the flow and heat transfer in a helical coil laminar transitional regime under mixed convection conditions is presented. The continuous separation reattachment boundary layer caused by wire coil, that interrupts near tube all, swirl induced shape insert, are identified as mechanism for enhancement. Simulations Reynolds number range 200<Re<1500 show role on transfer, dynamics sensitive to buoyancy forced wall heating. interaction secondary with motion investigated...
