Method for reducing pressure loss in connection with transport of fluid in pipes/ducts

摘要

A method is described for controlling pressure loss in connection with transportation of fluid in a pipeline (1) by controlling electrical charge concentration in fluid and/or pipeline. According to the invention the fluid is supplied with an electrical charge from at least one electrode (2, 3) arranged in the pipeline (1), at least the pipeline's (1) inner wall being made of a material which is capable of absorbing a charge from the fluid and retaining this charge, with the result that the amount of similar charges in the pipeline's (1) wall and the fluid is increased, thereby creating electrical repulsive forces between fluid and pipe wall. By this means the friction between pipe wall and fluid is reduced.
