“…Formulated models are computed with aid of Mathematica 11 using Parametric ND Solve, and then a detailed comparison have been made between those two models. The main significant outcome is abstracted as follows: Concentration production parameter has opposite effect on pressure rise in the retrograde pumping region. Pressure gradient increases by increasing Hartmann number for both models. Thermophoresis parameter, Brownian motion parameter, and Prandtl number are increases function in temperature of fluid.

This paper examines the influence of magnetic field on peristaltic flow of synovial nanofluid in an asymmetric channel. Hall current, thermophoresis, and Brownian motion effects are taken into account. Our problem is discussed for two models, in the first model which referred as Model (I), viscosity is considered exponentially dependent on the concentration, and Model (II) Shear thinning index is considered function of concentration. The governing problem is reformulated under the assumption of low Reynolds number and high wavelength. Resulting system of equations are solved numerically with the aid of Parametric ND Solve. Detailed comparisons have been made between Model (I) and Model (II) and found unrealistic results between them. Results for velocity, temperature and nanoparticle concentration distributions as well as pressure gradient and pressure rise are offered graphically for different values of various physical parameters. It is found that the velocity of fluid decreases in semi‐curved lines in case of Model (I) with the increase of Nb while, in Model (II) it decreases in the left side of the channel and increases in the right side of that channel. Such models are applicable to rheumatoid arthritis treatment.

“…Even with the same API gravity, an estimation from general viscosity trends will result in a significant error due to the varying composition. 6 The properties of many crude oils under reservoir conditions are well studied. 7 Due to the low temperature in an oil and gas plume in the deep sea, the focus of this work is on viscosity and density data at temperatures below 308 K. While the temperature of the hydrocarbon mixture inside an oil reservoir and directly at the point of discharge can significantly exceed this temperature, in the case of the Deepwater Horizon oil spill, the oil and gas mixture is reported to be rapidly cooled to 288.5 K. 8 In the evolving jet, the temperature of the oil and gas is further quickly lowered to background conditions.…”

An extension of a conventional apparatus is presented and applied in order to measure viscosities and densities of pure and gas-saturated liquids at elevated pressures. The viscosity of n-decane at pressures up to 10 MPa is shown to deviate less than 1% from literature values. Viscosities and densities of a light sweet crude oil are reported at pressures in the range of atmospheric to 23 MPa and from 268 to 308 K. Both viscosity and density of pure hydrocarbon liquids increase as a function of pressure, while they decrease as expected in the presence of dissolved methane. For seawater, an abnormal behavior is found with respect to the pressure dependency of the viscosity.
