Charge-to-mass ratio of individual blowing-snow particles [PDF]
Annals of Glaciology, 1998 Determining the electrostatic force acting on saltating snow particles requires knowledge of the electric field in the saltation region and the charge on the particle. To date, measurements of average charge-to-mass ratios for blowing-snow samples have been made but Schmidt and Schmidt (1993) have indicated these may underestimate ...

Numerical simulation of blowing ratio effects on film cooling on a gas turbine blade [PDF]
WIT Transactions on Modelling and Simulation, 2011 This article investigates the film cooling effectiveness and heat transfer in three regimes for a film-cooled gas turbine blade at the leading edge of the blade with 45 0 angle of injection. A Rolls Royce blade has been used in this study as a solid body with the blade cross section from Hub to Shroud varying with a degree of skewness.
