Pressure on Amusement Park Riders Courtesy of Vekoma Rides Manufacturing BV www.vekoma.nl Information Vekoma Rides Manufacturing B.V. is a two forms, but gradually energy is lost overall aerodynamic drag of the train. market leader in the global to friction and air resistance, and the While extensive streamlining of the first The Netherlands amusement industry in the design and latter can affect the speed and length carriage may reduce its wake, it can manufacture of family coasters, thrill of the ride. As modern roller coasters also lead to more exposure of the Leeghwaterstraat 21 coasters, and family attractions. become faster and the rides longer, second carriage to the undisturbed 2628 CB Delft Boasting a wide product range, the structures increase in size.

Based on the CFD results, a redesign of the seat shape was done that balanced the operating requirements and resulted in a significant performance improvement. A roller coaster is essentially a gravity- powered train. When the train is pulled up the first hill, gravitational potential energy is transferred to the train. Once the train begins to descend, the gravitational potential energy gets transferred to kinetic energy, the energy of motion. During the ride, The CFD simulations indicated that the there is a continuous conversion of size and shape of the wake behind the energy back and forth between the leading carriage is critical for the .
