viscous dissipation but neglected chemical reaction of the species. Ghaly and Seddeek [11] have investigated the effect of chemical reaction, heat and mass transfer on laminar flow along a semi-infinite horizontal plate with temperature dependent viscosity. The mass transfer with chemically reactive species for two classes of viscoelastic fluid over a porous stretching sheet is discussed by Cortell [12]. Andersson et al. [13] discussed the

In a high precision machining operation, lubricant is extensively needed to remove the heat at the tool-workpiece interfaces. High heat is generated at the interface due to friction between the tool and the workpiece, which can lead to a very poor workpiece surface quality and tool wear. For that reason, report showed that approximately 320,000 tons of lubricant were used per year in the European Union [1] proving the importance of lubricant in machining application. Lubricant is divided into three

Chevron Delo Service Oils (SAE 10W-30 400 XLE Synblend) Chevron products Company, a Chevron U.S. A Inc. division, maker of the Delo(R) brand of technologically advanced heavy duty engine oils, lubricants and coolants, unveiled a new category of heavy duty motor oil designed to address the growth of severe duty applications in on-and off-highway markets. Quality heavy-duty engine oils must also disperse soot and control sludge in order to help guard against the loss of an engine’s life. Properly lubricating

and accidently cut his hand when the flask hit the table. Review attached accident report in the appendix for further detail of the accident. During the first lab period, after the accident was cleaned up, we were able to obtain four density and viscosity measurements for both water and propylene glycol at different temperatures. For the pipe flow experiments, we were able to complete eight trials for turbulent flow experiment, twenty trials for the pump performance experiment, and five trials for

ADE can be used to transfer a range of solvents with viscosity ranging from 0.3 to 10 centipoise. The technology is also capable of working with volatile liquids such as ethanol and acetone which have low viscosity and surface tension. The ADE technology can effectively transfer a range of solvents with varying viscosity effectively with low coefficient of variation (CV). The CV is as low as <8% when the plate has unknown water and/or

Background The oil spills from an off-shore oil rig or tanker can do tremendous damage to the esosystem in the area of the spill and expand over vast regions to affect coastlines and indigenous wildlife hundreds of miles away. Cleaning oil spills, especially in a marine environment is important and it is a challenging task. The methods currently used to clean oil in water can be divided into following categories: using booms and skimmer; using oil solidifier and dispersants; adding biological agents

inhomogeneous deformation, which leads to the appearance of discrete and thin shear bands, resulting of its non-hardenable nature (KAWAMURA et al., 1997). However, in the supercooled liquid region, (ΔT), BMGs usually exhibit a drastic reduction of viscosity, and therefore, present a Newtonian flow behavior (WANG et al., 2005), and can retain its amorphous structure even after large plastic deformation (KIM, MA, and JEONG, 2003). Kawamura et al. (1997) studied superplasticity of a bulk Zr65Al10Ni10Cu15

magnetohydrodynamic flow of an incompressible non-Newtonian power law nanofluid due to a uniform rotation of an infinite disk is studied with heat and mass transfer. The thermal conductivity has been assumed to obey the same nonlinear rheological model of the viscosity function; as well as, the viscous dissipation has been comprised in the energy equation. The governing PDEs are reduced to a set of ODEs; using the generalized Von-Karman similarity transformations; for which finite difference numerical scheme is

balance between gravity and viscous forces is given by Where, • Tu is the Temperature of the top plate • Tb is the Temperature of the bottom plate • L is the height of the container. • g is the acceleration due to gravity. • ν is the kinematic viscosity. • α is the Thermal diffusivity • β is the Thermal expansion coefficient The critical Rayleigh number (RC) is the threshold over which the convection cells appear. RC ~ 1100.65 for a Marangoni set up with controlled boundary conditions. Rayleigh-Bénard
