...you can't beat the gas mileage! It all started in 1982 when Hans Tholstrup and Larry Perkins built a solar-powered car and drove it across the entire continent of Australia. Driven by the success of their vehicle, aptly named "Quiet Achiever", they encouraged others to push the limits of alternative energy vehicles. Five years later, the very first World Solar Challenge was born. Every other year since, teams from across the globe - prominent universities and private organizations alike - converge in Darwin, Australia to make the 3.000 km trek south to Adelaide in their solar-powered vehicles using regular ol' public roads and minimal camping gear for the seven-day journey.
Lubrication Flow within On and Off Highway Vehicle Gear Boxes
Transmissions and axles include gears, bearing and shafts to transmit power from the engine to the wheels. Under stress, these parts can become damaged or degrade in performance due to heat caused by friction. However, as increased amounts of oil are used, the gear churning torque will increase. These churning losses are directly related to loss of power and have a negative impact on fuel efficiency. By modifying the casing, or introducing baffles, oil can be guided to critical regions while decreasing the churning loss. In test rigs, it is difficult to visualize the flow inside the box for...
Dental Cement Simulation
Virtual prototyping using STAR-CCM+® of a complete implant, cement and crown system.
DFBI CFD simulation of boat bouncing off harbor wall
The boat is reacting to the buoyancy forces due to the water, gravity, two catenaries , and most importantly the contact coupling model which prevents it from passing through the harbor wall.
One of the great things about working for CD-adapco is that I get to see a lot of cool animations that illustrate the exciting capabilities that are coming soon in STAR-CCM+. The frustrating part is that usually I can’t share these with you until just before the new feature is released. Which is why today I’m excited to show you two of my favorites, which I find myself watching over and over again. Both videos illustrate the new contact model for the DFBI (Dynamic Fluid Body Interaction) solver in STAR-CCM+ v9.04, which allows you to directly model contact and collisions between moving bodies and boundaries.
DFBI CFD simulation of ball valve with contact and collision
DFBI CFD simulation of ball valve, using contact and collision modeling
STAR-CCM+® used to better understand the challenges of running engineering simulations on the clusters of tomorrow. New York and London. June 11, 2014 CD-adapco™, the largest privately held CFD focused provider of Computer Aided Engineering software, announced today a long term collaboration project with the High Performance Computing Center Stuttgart (HLRS) and SICOS BW. The aim of this ongoing project is to benchmark, profile and ensure the best STAR-CCM+® performance and scalability possible on petascale computing systems. STAR-CCM+® will initially be run on the 1.045 PetaFlop (113,000...

Understanding Fluidization: Two Approaches, Eulerian and Lagrangian
Fluidization is a common phenomenon within the chemical process and pharmaceutical industries. It is the process by which particles under certain conditions are made to behave like fluid. This phenomenon is found in fluidized bed reactors, fluidized combustors, catalytic cracking and tablet coating. Fluidization is a complex phenomenon to understand, visualize and perform experimental measurements. The design, operation and optimization of equipment using fluidization can indeed be difficult. A combination of observation, measurement and simulation can overcome and achieve this goal. This...
