Abstract: A spoiling apparatus for triggering a turbulent transition by autonomous disturbance and spoilers. The spoilers are mounted in multiple grooves in the circumferential direction of a navigating body, when a flow autonomously undergoes a turbulent transition, the spoilers remain in the grooves, the surface of the navigating body is free of protrusion, thus causing no additional flow resistance. A rated critical Reynolds number is set, in a case of a reduced flow speed and reduced density, the flow is a laminar flow, at which time the pressure applied to the spoilers by the flow is reduced, and the spoilers are ejected under the effect of compression springs. When ejected, the spoilers disturb the flowing of the bottom layer of the flow, and trigger the laminar flow into a turbulent flow.

Abstract: A weight loss composition consisting of 1 to 10 weight parts of L-hydroxy citric acid and 1 to 10 weight parts of L-carnitine tartrate as active components, and pharmaceutically or food-acceptable carrier is disclosed. The present composition can be made to tablet, capsule, oral juice or chewing gum which shows great effect of weight loss.
