Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

Hall thrusters, the most common type of electric propulsion system, typically use xenon as
the propellant, given its inertness, its ability to be stored at a high density under pressure …

Fluid properties. Units. Kinematics, dynamics of fluid motion: concepts of streamline, control
volume, steady and one-dimensional flows; continuity, Euler, Bernoulli, steady flow energy …

This study compares the tribological and thermophysical features of the lubricating oil using
MoS2 and ZnO nano-additives. The average size of MoS2 and ZnO nanoparticles were 90 …

In this research, two different diesel oil-based nanofluids were prepared and the influence of
temperature and nanoparticle content were examined on viscosity, tribological, and …

The main objective of this research is to study the tribological and thermophysical behavior
of ZnO nanoparticles as an additive at different weight percentages (0.1%, 0.4%, and 0.7%) …

Fully developed incompressible turbulent pipe flow at bulk-velocity-and pipe-diameter-
based Reynolds number ReD= 44000 was simulated with second-order finite-difference …

The route to turbulence in pipe flow is a complex, nonlinear, spatiotemporal process for
which an increasingly clear understanding has emerged in recent years. This paper …

A thermal heat-pump grid storage technology is described based on closed-cycle Brayton
engine transfers of heat from a cryogenic storage fluid to molten solar salt. Round-trip …

Thermophysical and tribological properties of traditional lubricant has important role in
proper performance of industrial equipment and transportation vehicles. Diesel oil is wide …
