2020年10月27日 · Judging from its name, the flow deflector should “deflect” the flow. In reality, the flow accelerated through the gap between the flow deflector and the wheel induces a pressure drop that sustains throughout the rear surface of the wheel, supported by the pressure distribution around the central circumference of the wheel, shown in Figure 3.

2023年10月1日 · The flow field around the wheels of a car is studied in a full-scale wind tunnel. The drag is reduced for a tyre with a more narrow sidewall. Combining a narrow sidewall with a narrow tread increases drag.

2024年2月9日 · You can look at flow formed wheels like improved cast wheels, as they're designed to be stronger than regular wheels while using a forging-like technique - this allows them to maintain a lighter weight while retaining most of the strength, and that also gives flow formed wheels some really cool designs that don't sacrifice any functionality.

2007年8月1日 · Road vehicles, especially their wheels and wheelhouses are bluff bodies, characterized by large regions of flow field influenced by boundary layer separation. The resultant flow field is a complex, 3D flow field.

2019年7月31日 · Cast, flow formed or forged, you have your options when it comes to wheels for your car. Vehicle weight, tire treadwear rating and use (autocross, road racing) will help you determine what wheel is the best for your hot rod.

2019年8月1日 · Aluminum wheels can be made by several different techniques. The most prevalent are casting, forging, and flow forming. Casting and forging are unique. Flow forming uses a combination of both. Cast wheels have somewhat of a bad reputation for ultimate strength, but that reputation was earned by poor quality wheels from substandard suppliers.

Two main areas where discrepancies between CFD and wind tunnel tests are present are wheel aerodynamics and cooling ow. Wheel aerodynamics has been the focus of CFD research for several years, especially with the expected introduction of the Worldwide harmonized Light vehicles Test Procedure (WLTP) regulations.

The paper reports results of the investigation carried out around an isolated wheel, both rotating and stationary, with a fixed ground plane. The wheel flow field was mapped by means of a 14-hole probe. Furthermore, new software, developed for the new traversing system, was used to allow the probe to accurately follow the wheel contour.

2023年10月26日 · Flow forming, also known as spin forging or flow forging, is a specialized technique used in the production of alloy wheels. It involves the application of high-pressure forces to shape and stretch a wheel's outer barrel, resulting in a stronger, lighter, and more durable final product.

2023年11月10日 · Flow forming wheels enhance the overall performance and safety of a vehicle. The reduced weight achieved through the flow forming process translates into quicker acceleration, improved braking, and enhanced maneuverability. Lighter wheels also contribute to better suspension response, reducing the strain on the vehicle's components.
