Pulsatile flow of blood in constricted narrow arteries under periodic body acceleration is analyzed, modeling blood as non-Newtonian fluid models with yield stress such as i Herschel-Bulkley fluid model and ii Casson fluid model. The expressions for various flow quantities obtained by Sankar and Ismail 2010 for Herschel-Bulkley fluid model and Nagarani and Sarojamma 2008 , in an improved form, ...

a mathematical model is described and applied for adsorption process of ethyl acetate from supercritical co2 stream on activated carbon particles. this model has the ability of illustrating variation of effluent concentration towards different parameters such as flow rate, temperature and pressure. in this research, a vast area of operational conditions is experienced. mass transfer resistance ...

objective(s) air pouch is a well-established inflammatory model in which fluid extravasations; leukocyte migration, angiogenesis and other parameters involved in the inflammatory response can be measured. in this study, the influence of gender on inflammatory parameters has been examined in the air pouch model. materials and methods to induce air pouch, adult male and female wistar rats were an...

in this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. a numerical method, discrete singular convolution (dsc), which seems to be efficient and simple, has been used to model the mixed boundary conditions. after a brief introduction, dsc is applied to model the equation of motion of fluid-structure with constant cross section subjected to el-centro (1940) earthquake...

In this paper, we have continued doing a research project which had done previously. Three types of power plants include an Organic Rankine Cycle (ORC), a Dual-Fluid-Hybrid (DFH) and a single-fluid hybrid-fueled (HYB); were re-modeled. After model validation, thermodynamic studies and exergy analysis were extended for the defined cases using the first and second laws of thermodynamics. Then the...

Obtaining samples that represent original fluid of reservoirs optimizes reservoirs management. The optimized management increases recovery. Also, selecting and performing proper Improved Oil Recovery (IOR) or Enhance Oil Recovery (EOR) programs depend on collecting representative samples. Achieving accurate compositions of original in-situ fluid prevents overdesigning surface facilities. Re...

force convection heat transfer of turbulent nano fluid flow in 90 and 60 degree elbow is simulated by using fluent. single phase model has been implemented to study such a flow field and standard

This paper considers an important model of boundary value problem with a condition at infinity namely combined free and forced convection over a plane of arbitrary shape embedded in a fluid-saturated porous medium; this model admits dual solutions, and uses a technique, which is to some extent modification of homotopy analysis method (HAM), in order to obtain dual solutions analytically with hi...

in this study, nonlocal nonlinear instability and the vibration of a double carbon nanotube (cnt) system have been investigated. the visco-pasternak model is used to simulate the elastic medium between nanotubes, on which the effect of the spring, shear and damping of the elastic medium is considered. both of the cnts convey a viscose fluid and a uniform longitudinal magnetic field is applied t...
