I got a new laptop and decided to see if it can handle the tasks I usually run on a workstation or computer cluster. It worked well. Using the Discrete Element Method (DEM) coupled with CFD in Simenter STAR-CCM+ 2210, I simulated the primary reverse flow cyclone feeding larger size catalyst particles back into a fluidized bed reactor.

we quantified the correlation of #flow-barrier height ratio in conjunction with #Froude #number #Fr with impact load, barrier deflection, and equivalent barrier stiffness based on coupled #CFD-#DEM #simulations of #debrisflow #impact on a #flexible #barrier. We recommend this height ratio be used as a design index in addition the prevailing #Froude #number based models. The animation compares two cases of height ratios with same incoming flow velocity but rather different #impact #mechanisms.

The student laboratory in the University of Southampton Towing Tank last week was to test a high-speed planing motor yacht hull form, with and without interceptors deployed at the transom. This is a 6 m/s run with no interceptors. It was good to be using the tank at higher speeds than in other recent student labs.

what is Froude Number?
In continuum mechanics, the Froude number is a dimensionless number defined as the ratio of the flow inertia to the external field. The Froude number is based on the speed–length ratio which he defined as Froude equals flow velocity divided by sqrt of gravity multiple characteristic lengths.

applications of CFD in the engineering world
Computational Fluid Dynamics (CFD) is a branch of engineering that deals with the numerical analysis and simulation of fluid flows. CFD has revolutionized the design and analysis of fluid systems by providing a cost-effective and efficient means of testing and optimizing designs before physical prototypes are built.

Courant number in CFD
The Courant number (CFL number) is a dimensionless quantity that relates the time step size to the spatial grid size in numerical simulations. It is commonly used in Computational Fluid Dynamics (CFD) to ensure numerical stability and accuracy of simulations.

Water channel flow visualization experiments are performed on a three-dimensional model of a small hill. This experiment was part of a series of measurements of the complex fluid flow around the hill using all available measurement techniques. The data will be used to improve basic understanding and CFD code development/validation.

In Computational Fluid Dynamics (CFD), numerical methods are used to solve the governing equations of fluid motion. The choice of numerical method depends on the specific problem and the computational resources available. Three common numerical methods used in CFD are explicit, implicit, and semi-implicit methods.

Simulations can bring things to light that are usually hidden from our eyes. Even seemingly simple processes from everyday life, such as the convective cooling of a hot cup of tea, turn out to be quite complex upon closer inspection.

The selection of time step in Computational Fluid Dynamics (CFD) simulations is a critical step that affects the accuracy and stability of the simulation. The time step should be small enough to capture the important flow features, but not so small that the simulation becomes computationally expensive or unstable.

"The world is non-linear, it’s true.
But fear not, for here is a clue:
When signals are small, and stabl’ overall,
x' = Ax will do."

This simulation illustrates the application of electro-osmosis for use with micro-pumps. By creating a series of deep slots in a microchannel, and then applying a potential across the channel, fluid flow can be controlled in a MEMS-scale pump. By adjusting the applied potential, the flow rate can be controlled.
