Electronics Cooling Fluid Comparison Study

symscape — Tue, 11 Sep 2012 20:07:47 +0000

Your choice of cooling fluid for an electronic device, can have a profound effect on its overall design and operation costs. So it's interesting to note that recent cooling strategies for computers include immersion of the entire computer in mineral oil as a cost-effective alternative to traditional air cooling. Which strategy do you pursue? Let CFD guide your decision - it is easy to switch the cooling fluid in a Caedium CFD simulation so you can make easy comparisons.

Loheed Technologies Evaluates Caedium for Marine Applications

symscape — Wed, 25 Jul 2012 14:12:16 +0000

Richard Loheed is an accomplished marine engineer, with over 20 years of experience in the design of advanced control systems for marine vehicles. Looking to enhance the consultancy services offered by Loheed Technologies, Rick recently began evaluating Caedium Professional for marine CFD applications.

CFD Analysis of a Sail Yacht from SketchUp

symscape — Thu, 17 Nov 2011 20:45:21 +0000

A sail yacht is a great example of an aerodynamic vehicle that relies totally on the wind for propulsion. And you guessed it, where there's aerodynamics there's also an opportunity for Computational Fluid Dynamics (CFD) to make an impact. CFD has been a primary tool in the aerodynamic optimization of many recent sail yachts. This is especially true in competitive sail yacht design, such as the yachts that compete for the America's Cup. If your budget doesn't extend to the scale of Larry Ellison's then fear not, you can still benefit from CFD analysis of your yacht design in combination with Google SketchUp and Caedium Professional.

Aerodynamic Study of a Kyosho Mini-Z RC Model Racecar

symscape — Fri, 29 Jul 2011 16:02:31 +0000

Kyosho Mini-Z RC model racecars are 1/27 scale and race at speeds up to 10 m/s. Fernando Freitas races them as a hobby and was wondering about the effect of aerodynamics on his car's performance. Fernando was aware of Computational Fluid Dynamics (CFD) and thought it might help him satisfy his curiosity. At the same time Fernando came across Caedium Professional and, with a free 30-day trial, set to work. Fernando remarked:

"I found it [Caedium] to be extremely useful and easy to use."

CFD for Solar Panels

symscape — Wed, 02 Feb 2011 00:54:58 +0000

Solar panels are solid-state, right? No moving parts and certainly no fluid flow - unless you count the rivers of electrons flowing in a semi-conductor. So what role is there for Computational Fluid Dynamics (CFD)? Once installed, how can you be sure that those brackets holding the panels in place are strong enough? Or even if your roof is strong enough to cope with the wind loading on the solar panels? Remain calm, CFD is here to help in the form of Caedium Professional.

F1 in Schools World Finals CFD Analysis

symscape — Thu, 16 Sep 2010 16:07:19 +0000

Brett Sizeland and his Basilisk Performance team won the Australian F1 in Schools title in March 2010, helped by Computational Fluid Dynamics (CFD) simulations performed in Caedium Professional. However, it doesn't end there, by winning the Australian title the team qualified for the F1 in Schools World Finals to be held September 20-22, 2010 in Singapore. Without pausing for breath, Brett set about designing a new car, with help again provided by Caedium CFD simulations.

Screencast of Flow Through a Pipe into a Box

This screencast shows how to use Caedium Professional to create the geometry and simulate a steady-state turbulent CFD simulation of air flow through a pipe into a box. Also you will see how to create velocity vectors and particle tracks within the flow volume and monitor residuals as the simulation converges.

Open Wheel Race Car CFD Analysis

Open wheel race cars, such as those found in Formula 1 (F1), are characterized by complex aerodynamics. With geometry preparation, meshing, physics setup, solver control, and results extraction all combined in a single unified simulation environment, Caedium Professional is a good choice for assessing the aerodynamic performance of such cars using Computational Fluid Dynamics (CFD).

Electric Race Car CFD Analysis

Many see the future of automobiles to be electric, so it's only natural to assume that the same may apply to motor racing. Luke Horsfall is one who believes electric race cars have a bright future, having set up Horsfall Racing (along with Laura Horsfall) to build electric race cars and race them in the F24+ electric race car class in the UK. The restrictions of this particular formula keep budgets and speeds relatively low (at least by Formula 1 standards). Making best use of the limited power in F24+ is crucial, and that places the emphasis on low-drag, aerodynamic race cars. I bet you can guess where this is heading - this is territory ripe for Caedium's Computational Fluid Dynamics (CFD) capabilities.

F1 in Schools Dragster v2.0 CFD Analysis

symscape — Wed, 03 Mar 2010 15:15:14 +0000

After reviewing the Caedium RANS Flow results posted in "CFD Analysis of an F1 in Schools Dragster," Brett Sizeland, Basilisk Performance team's chief designer, has been busy updating his F1 in Schools CO2 dragster design. Using the same geometry preparation process, physics setup, and post-processing, all within Caedium's unified simulation environment, we were able to rapidly perform the new simulation and extract the flow results presented here.

F1 in Schools Dragster CFD Analysis

symscape — Tue, 09 Feb 2010 15:50:52 +0000

F1 in Schools is an international competition for student teams (aged 9-19) to design, analyze, build, and race CO2 jet-powered cars (dragsters). Beyond promoting Formula 1 (F1) to the next generation of fans, F1 in Schools aims to give a flavor of running an F1 team by exposing students to finance, marketing, and engineering. Of course the most exciting area (as in F1) is engineering, where students get to use state-of-the-art 3D CAD/CAM software to design and build their dragsters. Performance optimization through analysis of the dragster design is also encouraged, which inevitably leads to Computational Fluid Dynamics (CFD).

Cyclone separators are used in many industries to separate particles from a fluid, where the fluid is usually air or water. The types of particles vary widely, from wood chips to dust. You can find cyclones in a variety of places and industries.
