Mathematical modeling demonstrates that nozzle distribution on drillbits affects the performance of the drilling fluid flow from the bit. This article is about the internal flow of nozzles on a rotary ...

When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...

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 ...
