An experiment has been performed to utilize the wasted and disposed fish from White Nile River after simple heat treatments (Sun drying, roasting, direct boiling and indirect boiling) in layers’ rations from 19 up to 40 weeks to replace the imported concentrate with the levels of 0, 1.5, 3.5 and 5% for all heat treatments. The crude protein of treated fish was 50.75, 52.50, 50.55 and 50.05% for...

The connectivity index chi can be regarded as the sum of bond contributions. In this article, boiling point (bp)-oriented contributions for each kind of bond are obtained by decomposing the connectivity indices into ten connectivity character bases and then doing a linear regression between bps and the bases. From the comparison of bp-oriented contributions with the contributions assigned by ch...

Self-rewetting fluids are commonly used in heat pipes, but their performance is not well understood pool boiling. Here, we performed boiling of n-butanol-water mixtures on thin titanium foil and utilized synchronous high-speed IR video cameras to capture transient temperature fields bubble dynamics. At the onset nucleate boiling, self-rewetting offered higher nucleation site density smaller dia...

When a physicist writes down equations, or formulates a theory in any other terms, he usually means not only that these equations are true for the real world, but also that the model corresponding to the real world is “typical” among all the solutions of these equations. This type of argument is used when physicists conclude that some property is true by showing that it is true for “almost all”...

A brief review of recent low gravity boiling research by investigators based in the United States is performed. Topics covered include bubble dynamics, nucleate pool boiling and CHF, transition boiling, boiling of mixtures, electric ˆeld eŠects, acoustic ˆeld eŠects, and ‰ow boiling. Planned research activities and recommendations for future

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...

Boiling heat transfer is a superior heat transfer technology using the latent heat transport with phase-change. However, it has been difficult to employ as a cooling technology for electronics because the unstable transition boiling and film boiling with excessive high temperature are impossible to control. In highly subcooled boiling, the coalescing bubbles formed on the heating surface collap...
