Windbreak fabric structures are special types of fabric structures that protect the environment from harmful chemical particles, abate wind erosion, and help to maintain valuable sources. In this example, the fabric is made of Porous Woven Polypropylene Fabric (PWPF) which has 40% porosity. These kinds of fabric structures show much more complex behavior rather than conventional fabric structures in wind simulation. Some structural engineering rules, such as load combinations and safety factors, ... need to be redefined regarding new approaches. The structural system consists of porous fabric, 3D truss, cables, pile caps, piles, and special instruments for connecting fabric to cable, ...

Finite element analysis of UOE manufacturing process of offshore pipes

UOE is a method used for production of longitudinally welded large diameter pipes. The UOE forming consists of [1] crimping, [2] U-press, [3] O-press, and [4] Expansion. The numerical simulation presented here demonstrates the U-press and O-press stages where large residual stresses can be observed.

Initial geometric imperfections of the pipe, as well as residual stresses and material anisotropy of the steel material, induced by the line pipe manufacturing process, constitute major factors for the mechanical behavior of the steel pipe. In the last decade, significant effort has been devoted in modeling the UOE manufacturing process, to predict the material properties of the UOE manufactured pipe and estimate its mechanical strength under external pressure.

You wont catch me hanging out at a #soccer game, nor watching the #worldcup2022 unless some friends are having a gathering. Not really a big fan of FIFA either. But I do love me some #aerodynamics, #cfd, and #datavisualization.

Over the past ten years at my job, I've practiced lots of problems on things that were just fun and interesting to me. Airflow around a spinning soccer ball isnt exactly new science, but its still beautiful.
Before working in this field I routinely heard things like "well the air moves faster on one side than the other" but that didnt really mean much to me until later in my education. I think showing it directly changes a lot!

Transient flows are always the 'real' problems in engineering. Start-up, shut-down, upsets... how often is every single line on your control screen completely flat? Never. CFD software demolishes the learning curve and slashes solving times. It's uses time-accurate LES turbulence combined with inherently parallelizable lattice-Boltzmann methods to solve 'impossible' problems on desktop GPU's in mere hours.

Watch below as the scalar gradient of methane is tracked in a buffer drum as the pulsating inlet flow pumps through the distributor. Diffusion of three scalars with an unsteady flow field.... Solve time? Six hours on a desktop RTX 3090.

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.
