Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...

The stress-from-heat problem involves a tube in a ceramic block. One surface of the block is uniformly heated. A first step of this sequential multiphysics analysis solves for the velocity profile.

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

This article discusses a number of problems that can be solved simply with an understanding of flow behavior without having to perform calculations. Given that most processes for shaping plastic and ...

Finite Element Methods (FEM) have emerged as a pivotal computational tool in the simulation of incompressible flows and the Navier-Stokes equations. By discretising the domain, these techniques offer ...

Petróleo Brasileiro SA (Petrobras) has used computational fluid dynamics (CFD), an analytical simulation tool for studying fluid mechanics, to determine possible causes of and solutions to ...

Scientific progress is not usually straightforward. Researchers pursue and abandon lines of inquiry. Results languish. Theories take decades to cohere. But sometimes the accumulation of scientific ...
