in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...

Simultaneous effects of slip and heat transfer on peristaltic transport of an incompressible electrically conducting viscous fluid  in an  asymmetric channel is studied under the assumptions of long wavelength and low Reynold number .The  asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitudes and phase.Exect solutions for stream function,velocity ...

the fluid flow and heat transfer in a three-dimensional microchannel filled with al2o3- water nanofluid is numerically investigated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity and pressure field in the momentum equations. the temperature fields, variation of horizontal velocity along the centre line of the channel, averag...

the fluid flow and heat transfer in lid-driven enclosures filled with cu-water nanofluid is numerically investigated. the moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity field and pressure in the momentum...

OBJECTIVES We sought to investigate the mechanisms of left ventricular (LV) intracavitary early diastolic flow during changes in contractility and loading. BACKGROUND There is limited understanding of how intracavitary flow velocities relate to intraventricular driving pressures. METHODS In 12 anesthetized dogs, we measured pressures in the left atrium (LA), LV at the mitral tip, apex, and ...

Onsager symmetry implies that a Brownian motor, driven by a temperature gradient, will also perform a refrigerator function upon loading. We analytically calculate the corresponding heat flow for an exactly solvable microscopic model and compare it with molecular dynamics simulations.

Glaucoma is a common progressive eye disorder and the treatment strategies will benefit from nanoparticulate delivery systems with high drug loading and sustained delivery of intraocular pressure lowering agents. Niosomes have been reported as a novel approach to improve drug low corneal penetration and bioavailability characteristics. Along with this, poor entrapment efficiency of hydrophilic ...
