EQUIPMENT FOR REGULATION AND VISUALIZATION OF TRANSITION BETWEEN LAMINAR AND TURBULENT REGIMES OF A FLUID.

摘要

Equipment for regulation and display oftransition between laminar and turbulent regimes of a fluid.;An experimental didactic system is proposedfor the regulation and visualization of the transition between regimeslaminar and turbulent flow of liquids in section ductscircular. It consists of a tank or bucket (1) that contains aliquid (2) that is evacuated through a discharge tube (5) thatIt has a nozzle (6) at its inlet and a discharge valve(7) on departure. The liquid level in the tank is regulated bya valve (3) and a level sensor (4). In front of the nozzle isinjects a flow of dye (10) through a needle (13) thatflows from a tank (11) regulated with a valve (12). Hedislodged liquid, along with the dye, is measured by aflowmeter (8) and collected in a discharge tank (9). Hasof various control and automation accessoriesexperiment.
