In a recent study, chemical and biological engineering professor Sujit Datta and fifth-year graduate student Christopher Browne discovered why certain fluids increase in flow resistance under pressure ...

New research shows that two types of turbulence coexist in everyday fluids like shampoos and ketchup, challenging long-held assumptions. Turbulence, the chaotic, irregular motion that causes the ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: Reyhaneh Farimani, University of ...

A review is given of a theoretical investigation of the flow properties of fluids in which the assumptions underlying the classical hydrodynamics of viscous fluids no longer holds. For an ...

For most fluids, an increase in pressure should lead to a burst of speed, like squeezing ketchup from a tube. But when flowing through porous materials such as soil or sedimentary rock, certain ...

New microscopy technique provides unprecedented insight into nanoscopic slip layers formed in flowing complex liquids. Whether it is oil gushing through pipelines or blood circulating through arteries ...

Suspension-based drag-reducing agents (DRAs) have proven to be an alternative to gel-based technology for ConocoPhillips Pipeline Co.’s US crude pipelines. This article examines data from one of ...

A study inspired by street performers making gigantic soap bubbles led to a discovery in fluid mechanics: Mixing different molecular sizes of polymers within a solution increases the ability of a thin ...

Fluid materials are classified broadly as simple and structured fluids. Simple fluids are materials consisting of a homogenous phase such as a pure substance or a solution. Materials consisting of ...
