An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...

Two-phase heat transfer is experimentally examined through vertical small diameter tubes, D =1.45 and 2.8 mm using water under a pressure of 50 to 81 kPa and a natural circulation condition. The pool boiling correlation by Stephan-Abdelsalam and the thermosyphon boiling correlation by Imura, et al. predict the measured experimental data in the 2.8 mm tube with an error of -30%. A large heat tra...

background central dialysate fluid delivery systems (cdds) are used by dialysis centers in japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. in japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

A lumped parameter model is developed to study performance of marine diesel engine thermal management system. One dimensional flow equations combined with classical Webie combustion model and Woschni heat transfer model are employed to describe diesel’s flow characteristic. Modeling results of heat release from diesel engine is validated against experimental data. Cooperated with experimental d...

Hydrophobic free energy for protein folding is currently measured by liquid-liquid transfer, based on an analogy between the folding process and the transfer of a nonpolar solute from water into a reference solvent. The second part of the analogy (transfer into a nonaqueous solvent) is dubious and has been justified by arguing that transfer out of water probably contributes the major part of th...

Water is a very important vital resource for all living organisms. A world without water can not be imagined. However the world is running out of its most precious resource. Water resources must be protected completely before the end of life on Earth, so today management of water resources has become the main agenda topic globally. Effective protection can be provided by sustainable water manag...
