Abstract

The hydrodynamic characteristics of a bend-type of water-jet pump for re- moving oils and solid materials with water are discussed theoretically and experimentally. This type of water-jet pump is composed of a bend and a water-jet nozzle. The water-jet nozzle is connected directly to the bend at the outside of bend. The transportation characteristics are derived theoret- ically using the countinuity, momentum and energy equations. The experi- ments for 45° bend-type of water-jet pump are carried out. The solid spheres with the specific gravity about 1.00 were used. The theoretically-predicted characteristics for removing solid materials agree well with the experimen- tal results. The experimental results for transporting various heavy oils are discussed comparing with the theoreti
