Original Abstract

Effort, to minimize losses of energy, is apparent in every branch of industry nowadays. Twenty per cent of whole energy is consumed for fluid pumping on the Earth. Fluid is delivered to its destination by a pipeline net. The hydraulic losses, in the pipeline net, are covered by pump power increasing. The T-part is one of sources of hydraulic losses. New mathematical model of T-part is presented in this paper. This model is suitable for both steady and unsteady fluid flow. Area influenced by bifuracation has been assessed. Two coefficients, which describe the losses in T-part, are defined. Results of 3D numerical model laminar flow in bifurcation are presented at the end of the paper.

Key words in English

mathematical model of T-part, hydraulic losses, unsteady flow, bifurcation of the flow,
