Numerical Analysis of Flow across Brush Elements Based on a 2-D Staggered Tube Banks Model

a comparative pragmatic analysis of the speech act of “disagreement” across english and persian

the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...

Numerical Analysis of 2 - D Ising Model

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

development of a 2-d numerical model for simulation of air distribution in high speed air water flow

in the present study a quasi 2-d numerical model is developed for calculating air concentration distribution in rapid flows. the model solves air continuity equation (convection diffusion equation) in the whole flow domain. this solution is then coupled with calculations of the free surface in which air content in the flow is also considered. to verify the model, its results are compared with a...

Flow and heat transfer behaviour across circular cylinder and tube banks with and without splitter plate

This paper describes the passive flow control of fluid in the downstream direction of the circular tube and in tube banks by means of splitter plate. Heat transfer and pressure drop depend on complex flow pattern of fluid in tube banks, whereas pressure drop linked directly with the fluid pumping capacity. A primary focus is to review experimental, analytical and numerical works that had been c...
