How iceberg shape affects melting is investigated in a combined experimental and numerical study of ice warm salt water. Experiments show that, contrast to previous models, highly nonuniform---side melt rates can be up 3 times larger than bottom rates, vary significantly within each face. Numerical simulations reveal that vortices accelerate at high flow speeds, double diffusive effects matter ...

The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...

Although silicon technology can be adopted for the fabrication of microfluidic devices with high precision, the capital and operating costs for such technology is often prohibitively expensive. In recent years, many alternative methods have been advocated to reduce the cost of microfabrication but often with reduced qualities in many important features, such as channel resolution, surface smoot...

As an extension of our previous study, the flow and mixing characteristics of a serpentine mixer in non-creeping flow conditions are investigated numerically. A periodic velocity field is obtained for each spatially periodic channel with the Reynolds number (Re) ranging from 0.1 to 70 and the channel aspect ratio from 0.25 to one. The flow kinematics is visualized by plotting the manifold of th...

channel flows have three components of velocity, 1component in flow direction and 2components in spanwise of channel. because of heterogeneity of velocity undulations, in the channel section the vortices are formed that are nominated “secondary current cells”. these cells cause the lateral shear stress in the channel walls and introduce the erosion and scour of the channel walls. heterogeneity ...

• Forced convection heat transfer in a rectangular channel with angled ribs is studied. Longitudinal have been inserted order to improve thermal performance. Friction/heat characteristics are experimentally and numerically evaluated. One longitudinal rib at the midline increases Two not found further increase high aspect ratio (5:1) 45 deg has investigated. The periodically positioned on one wa...
