Most model lung surfactant (LS) monolayer (DPPC:POPG 7:3) work is done at room temperature, far below the physiological 37C. The reason for this is often that in addition to the experimental difficulties of working at higher temperatures, also model LS monolayers are highly fluid and unstable at these temperatures. Fluid monolayers collapse by flowing into the subphase through vesicles or disks...

In this paper, mixed convection of Al2O3-EG-Water nanofluid in a square lid-driven enclosure is investigated numerically. The focus of this study is on the effects of variable thermophysical properties of the nanofluid on the heat transfer characteristics. The top moving and the bottom stationary horizontal walls are insulated, while the vertical walls are kept at different constant temperature...

The purpose of this paper is to derive rigorously the so called viscous shallow water equations given for instance page 958-959 in [A. Oron, S.H. Davis, S.G. Bankoff, Rev. Mod. Phys, 69 (1997), 931–980]. Such a system of equations is similar to compressible Navier-Stokes equations for a barotropic fluid with a non-constant viscosity. To do that, we consider a layer of incompressible and Newtoni...

The focus of the present study is to examine chemical reaction and Joule heating effects on steady flow a viscous radiating fluid in porous medium under influence variable viscosity. viscosity assumed vary exponentially with temperature. governing equations ow, heat mass transfer are transformed into ordinary differential using appropriate similarity transformations. converted then solved numer...

In this paper, the effects of adding nanoparticles including Tio2 to a fluid media for purpose of free convection heat transfer improvement were analyzed. The free convection was assumed to be in laminar flow regime and the solutions and calculations were all done by the integral method. Water, as a Newtonian fluid, was considered the base fluid (water) and all the thermo physical properties of...
