In order to gain an understanding of the mechanism of thermal performance increase in the shell side, a shell and tube heat exchanger is proposed in this study. Numerical investigations of the shell side fluid flow and heat transfer are performed…

In this work, a numerical study of a coupled transient heat and moisture transfer was realized. The program developed is simple compared with those developed by other researchers in the literature. We have exploited it, to compare the evolution of…

This paper aims to investigate the influence of tube shapes on thermal-flow characteristics of sinusoidal wavy finned-tube heat exchangers. Two row staggered bundle with six geometries of tubes (four flat tube geometries, one oval tube and a circular…

This research paper aims to shed light on a scientific reality, to reveal the most important obstacles to the field of research in human and social sciences. As a way to study this reality, we have selected a research sample for this field which is…

The risk has a number of objective and/or subjective factors that can be recognized at any given time. This concept opens up new research prospects. An example of the risks associated with night shifts in hospital emergencies could be realized or…

Ernest Hemingway’s minimalist style, which is based on his “Theory of Omission,” has exerted a considerable influence on generations of writers. This article provides additional evidence with respect to his narrative influence on the short fiction of…

In this work, we show that the system of difference equationsxn+1=(ayn-2xn-1yn+bxn-1yn-2+cyn-2+d)/(yn-2xn-1yn),yn+1=(axn-2yn-1xn+byn-1xn-2+cxn-2+d)/(xn-2yn-1xn),where n belongs to the set of positive integer numbers, x-2, x-1, x0, y-2, y-1 and y0 are…

In this paper, the blow-up of solutions for a Dirichlet-Neumann problem to initial nonlinear viscoelastic plate equation with a lower order perturbation of p(x,t)-Laplacian operator in the presence of time delay is obtained. Under suitable conditions…
