Determination of laminar, turbulent, and transitional foam flow losses in pipes
In arriving at a method for predicting friction losses in laminar, transitional, and turbulent flow regimes for flowing foam, it was found Reynold's numbers and Fanning friction factors could be calculated with effective foam viscosity, actual foam density, average velocity, and ture pipe diameter. Further, it was found the relationship between Reynold's number and Fanning friction factor for foam was identical to that of single-phase fluids. The test data were taken under controlled flow in capillary tubes and 1-1/4 in. and 2-3/8-in. oil field seamless tubing. Friction losses of foam within 2-7/8-in. tubing and 4-1/2-in. and 5-1/2-in. casing during fracture treatments have been accurately predicted using the proposed method. (12 refs.)
