การลดแรงเสียดทานในการไหลผ่านท่อ: หลักการพื้นฐานและแนวทางประยุกต์ใช้ในประเทศไทย

Abstract

Abstract

Drag reduction phenomenon can be implemented by means of small polymer addition in pipe flow. As a result, amount of energy can be preserved and the flow rate can be increased for turbulent pipe flow systems, including pumps, water pipe flow, and water jets at pipe exits. Therefore, these special characteristics can be applied as technologies for solving problems involving pipe flow systems, such as flooding, water sanitization, and energy conservation in pump and industrial piping system.
