The first volume of this monograph included the formulation and self-similar solutions to blast waves. The next step in our exposition of Blast Wave Theory and Compu-tati,ns then expresses the need for presenting analytical solutions that, in effect, extend che range of validity of self-similar ones. The authors found that the one analytical method that is most amenable to solving different classes of problems ia the Quasi-Self-Similar Method developed by Oshima. It was then decided to devote the second volume of this series to presenting a complete exrosition to this nmethod that includes solutions to several types of problems, most are included here for the first time.

The present work aims at further understanding the details of heat transfer and flow regimes in flows around single cylinders and multi-tube banks with heat transfer, and is typically applied in heat exchangers. Computational Fluid Dynamics (CFD) tool is conveniently used for both design and analysis. Predictions of local flow and heat transfer characteristics in such complex geometries are made through the numerical solution of governing equations of mass, momentum, energy and species transports in the flow domain. The present work demonstrated the capabilities of CFD software to adequately predict flow regimes and heat transfer characteristics in different heat exchangers arrangement and their validity assessed by comparisons with previously published experimental data and simulation results. Various test case studies were performed and the obtained numerical results are compared to experiments. Good qualitative agreements were observed with some discrepancies in the vicinity of separation zones.
