Flow induced movement on a validated model with XFlow CFD

Posted by Dolf Broekaart on Aug 18, 2020 11:12:59 AM

In this blog we will discuss the process to determine movement of bodies due to a fluid flow, performed with XFlow CFD. As an example we have taken a historic measurement device called a "Wildse Vaan".

Hydrofoiling - Balancing virtually is as challenging as in practice

Posted by Dolf Broekaart on Jun 29, 2020 7:57:10 PM

This weeks blog is about hydrofoiling. One of my personal hobbies is watersports. I love sailing, windsurfing, wakeboarding and other challenging water related balance-sports. Normally I spend my summer in a warm country along the sea, or at least close to it. Due to Covid-19 we will stay in our own country this year, but there is still plenty sea along the shore of Holland. During the lockdown period, I watched some videos during the evening-hours on youtube where hydrofoiling is done for windsurfing & kitesurfing. Although I have never done it myself yet, it seemed a very cool thing to start trying out this summer. Being a Simulation addict, I first wanted to get an impression how dificult this is by virtually assessing the concept of it by use of SIMULIA XFlow CFD.

Performance assessment of a Peristaltic Pump

Posted by Nikolaos Mavrodontis on May 22, 2020 11:37:02 AM

In this blog post, we will be showcasing a fully coupled fluid structure interaction (FSI) analysis, of a peristaltic roller pump. This study will focus on assessing the performance of a peristaltic pump, under operation. This co-simulation analysis, will solve for both the structural and fluid domains' unknown quantities, during 1 revolution of the rotating mechanism of the pump.

This is an example of a challenging application, in which numerical modelling and computer simulations can provide a lot of insight and value.

The aspects we want to evaluate in this digital model are; determining the volume flow-rate for a given rotation speed, assessing contact stress areas on the tube, and determining the torque output for the given rpm.

Xflow CFD demonstrating the Magnus effect

Posted by Nikolaos Mavrodontis on Jan 2, 2018 8:46:46 AM

In the current post, we will be focusing on introducing XFlow CFD by demonstrating an aerodynamic effect primarily observable in spheres or cylinders following certain trajectories while spinning at the same time.

This effect is known as the Magnus effect, associated with spinning objects. A sphere for example travelling through mid-air while spinning at the same time , will drag air faster around one of its sides. This will consequently create a pressure gradient between the sides of the sphere, thus creating a lift force that will alter the sphere’s trajectory compared to a case with no spin.  The lift force generated is equivalent to that of an airfoil, only the origin of the necessary air recirculation around the body is by mechanical rotation (the spin)  and not by aerodynamic design ( the airfoil).

XFlow is a next generation CFD software based on the Lattice-boltzmann method designed for a broad range of computational fluid dynamics simulations. XFlow’s  latest release supports coupling with Abaqus for performing fluid structure interaction analyses.

The Magnus effect will be demonstrated with a spinning football analysis in XFlow.
