Predicting hemolysis is a mandatory task when designing blood flow related mechanisms. For decades, researchers have tried to estimate trauma in red cell (RBC) for applying assist mechanisms development, but the specificity and absence of more physical details limited models this purpose into ranges applications. This work aims present new method modelling considering stress threshold that RBC ...

2 A method for generating three-dimensional, time-dependent turbulent innow data for simulations of complex spatially-developing boundary layers is described. The approach is to extract instantaneous planes of velocity data from an auxiliary simulation of a zero pressure gradient boundary layer. The auxiliary simulation is also spatially-developing, but generates its own innow conditions throug...

Abstract. Modern wind-turbine airfoil design requires robust performance predictions for varying thicknesses, shapes, and appropriate Reynolds numbers. The airfoils of current large offshore wind turbines operate with chord-based numbers in the range 3–15 million. Turbulence transition boundary layer is known to play an important role aerodynamics these near operating point. While lack predicti...

We present results with a parallel CFD code that computes steady-state solutions of the Reynolds-Favre averaged Navier-Stokes equations for the simulation of the turbulent motion of compressible and incompressible Newtonian fluids. We report on preliminary experiments on 2D and 3D problems, for both internal and external flow configurations. In this communication we present numerical results wi...

This report presents the use of a time-marching threedimensional (3-D) compressible Navier-Stokes equation numerical solver with a one-equation turbulence model to simulate the flow fields developed along concave wall surfaces without and with a downstream extension flat wall surface. The 3-D Navier-Stokes numerical solver came from the NASA Glenn-HT code. The one-equation turbulence model was ...

Predictions of the flow over a wall-mounted hump are obtained using solutions of the Reynolds-averaged Navier-Stokes (RANS) equations and Detached-Eddy Simulation (DES). The upstream solution is characterized by a two-dimensional turbulent boundary layer with a thickness approximately half of the maximum hump thickness measured at a location about two chord lengths upstream of the leading edge....

The Flux Reconstruction Method/ Correction Procedure via Reconstruction (FR/ CPR) is a high-order numerical method for computational fluid dynamics. It combines the Finite Element method and the Finite Volume method, with a polynomial distribution of variables in a computational cell, and Riemann solver applied at the cell boundaries. The FR/ CPR method has a similar resolving ability to the fa...

The correlation between computational fluid dynamics (CFD) and experimental (EFD) is crucial for the behavior prediction of aerodynamic bodies. This paper’s objective twofold: (1) to develop a method that approaches commercial CFD codes their link with EFD in more efficient way, using downscaled model, (2) investigate effect rain on wing. More specifically, we one-phase two-phase flow over typi...

Abstract We introduce a framework for statistical inference of the closure coefficients using machine learning methods.

It consists two components. First, treating all latent variables (non-observed variables) in as st...

The problem of modeling the flow around an airfoil type transport vehicle near ground is considered. turbulent. Nowadays, most advanced mathematical models aerodynamics are based on physical properties a viscous compressible gas and Reynolds-averaged Navier – Stokes equations. Mathematical turbulent flows remains one challenging problems. Reliable prediction characteristics extremely important ...
