Abstract: This paper presents the formulation of a mechanistic model for slug flow in vertical pipes. The equations required to determine holdup, the relevant velocities and pressure loss are presented. ...

Abstract: The improved model developed in Part 1 for predicting heat losses and pressure changes in steam injection wells is evaluated. It shows good agreement with limited field data. The improved model ...

Abstract: An improved model for predicting heat losses and pressure changes in steam injection wells is presented. The model incorporates a new two-phase, annular-mist flow pressure change model with heat ...

Abstract: A review of the explicit friction factor equations developed to replace the Colebrook equation is presented. Explicit friction factor equations are developed which yield a very high degree of ...

Abstract: The steady and pulsatile flow of blood through small rigid, circular tubes has been analysed by a microcontinuum approach. The exact solutions for velocity and cell rotational velocity are ...
