Experimental analysis of the pressure–velocity correlations of external unsteady flow over rocket launchers [PDF]

open access: yes, 2013
Based on simultaneous wall pressure and velocity measurements, the aerodynamic load of a launcher body model is investigated. Two different configurations are considered in order to study the influence of geometrical artifacts on the after body flow and ...

The onset of instability in unsteady boundary-layer separation [PDF]

open access: yes, 1996
The process of unsteady two-dimensional boundary-layer separation at high Reynolds number is considered. Solutions of the unsteady non-interactive boundary-layer equations are known to develop a generic separation singularity in regions where the ...

Diffusion in Cauchy Elastic Solid [PDF]

open access: yes, 2022
It is commonly accepted that a starting point of the science of diffusion is the phenomenological diffusion equation postulated by German physiologist Adolf Fick inspired by experiments on diffusion by Thomas Graham and Robert Brown.

Diffusion in Metals and Intermetallics: An Overview [PDF]

open access: yes, 2022
After a few remarks about the history of diffusion in solids we remind the reader to some basics of diffusion such as tracer diffusion, interdiffusion, high-diffusivity paths, and basic diffusion mechanism in solids.

A conforming discontinuous finite element method for diffusion-reaction equations

open access: yes四川大学学报. 自然科学版, 2023
For the primal-mixed form of the steady diffusion-reaction equation, a new conforming discontinuous finite element scheme is proposed by using the idea of discontinuous finite element method and the least-square method. Then the method is extended to the

Experimental and Numerical Study on Micromixing by Utilizing the Movement of Gas–Liquid Free Interface

open access: yesJournal of Fluid Science and Technology, 2011
In this study, we discuss the development of a mixer that incorporates a moving interface formed by placing two gas–liquid free interfaces into a conventional straight-flow micromixer.

Study of Solid–Liquid Extraction Kinetics of Oil from Dried Avocado (Persea Americana) Flesh Using Hexane as A Solvent

open access: yesInternational Journal of Technology, 2023
In the present study, solid–liquid extraction of dried avocado flesh was investigated using hexane as a solvent for three pre-treatment methods (uncooked, cooked with CaCO3, and cooked with water) and two material sizes (8 mm × 5 mm × 5 mm and ...

High-Order Compact Difference Method for Solving Two- and Three-Dimensional Unsteady Convection Diffusion Reaction Equations

open access: yesAxioms, 2022
In this paper, a type of high-order compact (HOC) finite difference method is developed for solving two- and three-dimensional unsteady convection diffusion reaction (CDR) equations with variable coefficients. Firstly, an HOC difference scheme is derived

Self-Similar Solution of Unsteady Axisymmetric Stagnation-Point Flow of a Nanofluid Impinging on Oscillating Cylinder [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2023
The unsteady, viscous flow of Nanofluid in the vicinity of an axisymmetric stagnation point of an oscillating cylinder is investigated. The cylinder is moving toward or away from the impinging flow. The impinging free stream is steady and with a constant

Bi-directional stretched nanofluid flow with Cattaneo-Christov double diffusion

open access: yesResults in Physics, 2019
Bi-directional unsteady flow of nanomaterial has been explored in the existence of Cattaneo-Christov double diffusion. Brownian motion, thermophoresis and heat sources namely PST (prescribed surface temperature) and PHF (prescribed heat flux) are ...
