Thermal radiation enhances heat transfer, and it is used widely in manufacturing materials processing applications. Thus, steady two-dimensional boundary layer flow over an exponentially porous shrinking sheet of nanofluids was considered the influence thermal related to partial slip conditions suction. This paper aims study nanofluid penetrable with slip. The effects silver (Ag) nanoparticles ...

Thermal paper as a pyrotechnic source of thermal batteries is typically including combinations of barium chromate, zirconium and mineral fibers. For the deposition of barium chromate and zirconium microparticles on thermal paper, these should be dispersing in solution. In this study, dispersion of these particles in aqueous medium by using sodium dodecyl sulfate (SDS), Triton X-114, carboxymeth...

in many reservoirs, after water flooding, a large volume of oil is still left behind. hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.in the present work, the effects of injection rate and the temperature of the injected water were surveyed by using core flooding apparatus. water flooding was perf...

We study the influence of thermal boundary conditions on large aspect ratio Rayleigh-Bénard convection by a joint analysis experimental and numerical data sets for Prandtl number Pr=7 Rayleigh numbers Ra=105−106. The spatio-temporal are obtained combined Particle Image Velocimetry Thermometry measurements in cuboid cell filled with water at an Γ=25. In addition, generated Direct Numerical Simul...

High-order lattice Boltzmann methods provide an elegant and systematic way to incorporate thermal compressible effects represent a promising approach for the study of beyond-hydrodynamics regimes characterized by finite Knudsen numbers. However, presence multiple layers makes definition boundary conditions non-trivial, since one needs define missing information particle distributions across sev...
