Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

A phenomenological model is proposed in this paper for simulating the effect of wall friction in turbulent pipe flows.The flow in this model is divided into two regions: wall region and core region.

Fluid flow friction factors serve as a cornerstone in understanding and predicting the resistance encountered by fluids moving through conduits. These dimensionless parameters are essential in both ...

Anyone who has ever turned on a tap knows something about fluid dynamics. Whether a fluid is flowing through household plumbing or industrial oil and gas pipelines, when it runs slowly its flow is ...

Pore-scale mechanisms of drag reduction by micro-blowing have rarely been explored. A direct numerical simulation (DNS) study, published in the Chinese Journal of Aeronautics, is performed to uncover ...

Across many industrial and academic applications, it’s necessary to accurately measure liquid flow. Depending on the application, accurate measurements can be the difference between making a profit or ...

The “Blade” laminar flow wing demonstrator may reduce wing friction by 50%, improving fuel economy and reducing CO2 emissions by 5%. Airbus SAS completed the first test flight for its A340 ...
