Abstract:Surface tension of pure fluids, inherently decreasing with regard to temperature, creates a thermo-capillary-driven (Marangoni) flow moving away from a hot surface. It has been known that few high-carbon alcohol-aqueous solutions exhibit an opposite behavior of the surface t...

Abstract:Abstract(#br)A two-layer porous (fine and coarse) burner consisting of radiation corridors (finned rods) and an external preheater is numerically analyzed. The porous burner holds the flame and heats the finned rods effectively conducting heat to radiating disks downstream, while...

Abstract:Abstract(#br)The importance of pathologic features of metastatic lymph nodes (LNs), such as size, number, and extranodal extension, has been recently emphasized in patients with papillary thyroid carcinoma (PTC). We evaluated the characteristics of metastatic LNs identified ...

Abstract:Abstract(#br)A record radiation efficiency of 37% is achieved using a two-layered porous (SiC foam, fine and course) burner using multiscale thermal nonequilibria and effective heat recirculation. The porous burner holds the flame and heats finned SiC rods effectively conducting ...

Abstract:Abstract(#br)In this paper, we present an access network design problem with end-to-end quality of service (QoS) requirement. The problem can be conceptualized as a two-level hierarchical location-allocation problem on the tree topology with nonlinear side constraints. The object...

Abstract:Abstract(#br)An experiment-based, two-medium thermal model was developed to evaluate the thermal response and protective performance of permeable clothing systems under hot air jet impingement conditions. The clothing systems consisted of single- or double permeable fabric(s) and...

Abstract:Abstract(#br)Melatonin has been found in a wide range of plant groups. Its physiological roles have been suggested to be diverse in stress protection and plant growth regulation. An attractive hypothesis is that phytomelatonin acts as an auxin to regulate plant development. ...

Abstract:Abstract(#br)An experimental study was conducted to investigate the effects of solution subcooling and wall superheat on both sensible and evaporative heat transfer in a falling-film heat exchanger using both plain and porous-layer coated tubes. By varying the subcooling and wall...

Abstract:Abstract(#br)This paper discusses active flow control schemes for the cold-start performance enhancement of a pump-assisted, capillary-driven, two-phase cooling loop. A Proportional-Integral (PI) control algorithm was used to regulate the boiling condition (from pool boiling...

Abstract:Abstract(#br)The current efficiency of monolithic (including two-layer) radiant porous burners is less than 25% and here we introduce a novel structure for effective preheating and radiation routing to increase the efficiency. This recovers the flue gas heat to increase the inlet...
