Abstract A novel nonintrusive technique based on an air-coupled ultrasonic transducer was used to study the hydrodynamic behavior of falling film over metal foam layered horizontal tube. Copper having a porosity 90.5%, brazed copper tube 25.4 mm diameter in this study. Falling thickness distribution circumferential direction and dynamic characteristics were studied Reynolds number range 356–715, at spacing 5 15 mm. The tubes compared with that plain surface. Heat transfer studies evaporator...
Performance enhancement of horizontal tube falling film evaporators using thin metal foam was studied. A copper brazed over the outer surface a and used in evaporator desalination system. It observed that distillate production heat transfer rate enhanced by more than twice with modified tube. Effect feed rate, temperature, subcooling on studied for foam-wrapped exchanger evaporator. also to study effect scale formation. The effects flow seawater turbidity formation Total deposit weight after...
Waste heat capture from systems such as photovoltaics (PV) and refrigerators can lower their energy efficiency by increasing operating temperature. In this study, we evaluate evaporative cooling of the final effect along with internal recovery in a multi-effect diffusion distillation (MEDD) for producing pure water without negatively impacting waste-heat source. Lab-scale experimental results membrane module validate concept, showing that production be enhanced more than 20% while...
Novel designs of multi-effect membrane distillation (MEMD) are investigated for improved energy efficiency. A two-dimensional CFD model is developed with custom user-defined functions accounting water vapor transport from the feed to product channel study a permeate gap MEMD system. The gained output ratio (GOR) modular system comprising serpentine flow path across effects increases three times when number increased five. Preheat channels proposed increase inlet temperature entering first...
A modular multi-effect membrane distillation (MEMD) system is fabricated by assembling an array of machined plates to setup a serpentine flow feed across multiple effects. attached on one side each plate collect condensate, and flows over the other where it receives enthalpy condensation which drives further evaporation through next membrane. Compared vacuum-MEMD, this thin permeate gap operating at ambient pressure has simpler design with smaller footprint but likely lose more energy as...
Postoperative atrial fibrillation (POAF) is a frequent and severe complication following cardiac surgery. While obesity established as risk factor for (AF) in non-surgical settings, its role the postoperative period still debated. This systematic review aims to assess relationship between POAF patients undergoing A comprehensive literature search was conducted PubMed, Embase, Web of Science, Cochrane Library, focusing on randomized controlled trials (RCTs) published until June 2023.
