... (0.05 m/s < U co < 0.3 m/s) reduced the liftoff velocity of an attached flame. The reduction rate of the liftoff velocity with co-airflow was found to be more significant for the fuel nozzle with the smaller lip thickness. At a relatively higher coflow (U co > ∼0.3 m/s), a more pronounced drop...

...Brenton S. McLaury; Siamack A. Shirazi; Tim L. Burden Erosion is a complex phenomenon that depends on many factors such as fluid properties, solid particle properties, flow stream velocity, flow geometry, and type of metal. Flow modeling and particle tracking are important tools for predicting...

...Brenton S. McLaury; Siamack A. Shirazi One commonly used method for determining oil and gas production velocities is to limit production rates based on the American Petroleum Institute Recommended Practice 14E (API RP 14E). This guideline contains an equation to calculate an “erosional...

... are computed from characteristic curves which are functions of the penetration of the bit into the rock and the angular velocity of the bit. Numerical simulations show self-excited oscillations of the drillstring, including bit take-off from the bottom hole and large amplitudes in the bit’s angular velocity...

...Mamdouh M. Salama, Fellow ASME The current practice for eliminating erosional problems in piping systems is to limit the flow velocity V e to that established by the recommended practice API RP 14E based on an empirical constant ( C -factor) and the fluid mixture density ρ m as follows: V e = C / ρ...
