Swapping Fuel for More Beer on your next Caravan Holiday

Caravan owners are well aware that the speed they drive at and the shape of their caravan can greatly affect fuel consumption.
In partnership with Caravan World magazine, we've taken a closer look into the performance of caravans with the aid of CFD, including some less obvious factors that can help shave off the drag on your caravan and improve fuel consumption.

New & Improved: The 2014 FIA Formula One Series

    This weekend, televisions around the world will tune into to watch the first race of the 2014 FIA Formula One Championship take place in Melbourne, Australia. Of particular interest to all F1 fans will be the new looking cars with their revolutionary new power units. Formula One has undergone another drastic change in the rules, prompting engine manufacturers to clean-sheet design an integrated turbocharged electric-combustion powertrain system. Of course in addition to the new engine specifications, the governing body also revised the rules controlling the size and shape of the allowable external aerodynamics package. As a result of these rule changes, each team's aerodynamics departments have been forced to perform a complete overhaul of the aerodynamics of their car.  In this video, Australian driver Daniel Ricciardo and world champion Sebastian Vettel from Red Bull Racing explain the most significant changes to the 2014 FIA rules: As they are constantly striving to improve on-track performance, and given the extreme time constraints of competitive motorsport, the traditional product design process of "design-manufacture-evaluate-redesign" does not allow enough potential designs to be evaluated by F1 teams to remain competitive. By leveraging a Simulation Driven Product Design process, F1 teams are testing more designs in faster timeframes, and thus more efficiently working to optimise the final design and extract maximum possible performance within the new rules. Of all the engineering challenges present in F1 racecar engineering, this advantage is most prominent in the field of fluid dynamics: affecting both external aerodynamics and internal flows. Given that the engine dimensions and fuel tank size are now even more strictly controlled, in order for a team to get more power out of the engine than their competitor, they must put more fuel and air into the engine. For every tenth of a gram of air that the team can force into the engine per cycle, approximately 13 extra kilowatts of shaft power can be produced. While not all of that energy makes it into the rear wheels, the resulting increase in power is still immense. To deliver the most air into the cylinder, it is now legal for teams to compress the air by use of a turbocharger (a change which is welcomed by many fans who love that turbo sound!).  For optimum turbocharger design, engineers turn to ANSYS CFD and associated Workbench design tools such as the TurboTools suite which provides highly advanced integrated tools including BladeGen/BladeModeller, TurboGrid, special Turbo Pre and Post-Processing Macros as well as Vista tools.  ANSYS CFD allows turbocharger designers a faster turnaround on designs and works on templates that produce dependably accurate results. For external aerodynamics,  the advantage...
