Currently there are no effective methods of obtaining accurate fluid volume measurements in a microgravity environment. Conventional fluid measurement methods rely solely upon gravity to settle the fluid in order to obtain accurate measurements. However, this approach cannot be applied when fluids are within a microgravity environment and experience sloshing. This optical mass gauging system ut...

The Moment-of-Fluid(MoF)methodis an extension ofpopular Volume-ofFluid(VoF)techniquefor trackingmaterialinterfaceinmulti-materialfluidflows. VoFmethods trackthe cell-wise material volumes anduse these data for reconstructingtheinterfacesinmixedcell. TheMoFmethodgoes one stepfurther and, in additional to the volumes,keeps trackofthe cell-wise material centroids;this approachprovides sufficiently...

A new characteristic-based method is developed and used for solving the mixed and forced convection problems. The nano-fluid flow with heat transfer is simulated with a novel characteristic-based scheme in closed domains with different aspect ratios. For this purpose, a FORTRAN code has been written and developed. Water as a pure fluid and water-titanium dioxide as a nano-fluid were considered....

In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant.  Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...

In this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(V/V) percent of the reports. The overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...
