Background technique
Flow Visualization Technologies are hydromechanical important components, be the new flow phenomenon of discovery, explore flow mechanism,
It measures Complex Flows and analyzes the important means of its Characteristics of Flow Around, also there is important practical value in engineering.Modern age fluid force
It learns and develops and separate application of the stream in aircraft of new generation development with aerodynamic, Complex Flows (are divided for people
From stream, eddy-currents, turbulent flow, nonstationary flow etc.) researched and proposed new project, including its mechanism study and application study, this
A little Complex Flows be usually it is three-dimensional, unsteady, acyclic, fluidised form at any time with space and change, or with complexity
Space structure or flow-type are unsteady, and often the two haves both at the same time.Currently, people catch these Complex Phenomena in Vertical Bell Jar
The research caught with flow mechanism is also not enough, and wherein one of the major reasons are a lack of display and measure the means of Complex Flows.
Smoke-wire method is common method in FLOW VISUALIZATION experiment, implementation are as follows: in the upstream traverse one of wind tunnel model
The root metallic resistance silk thread vertical with incoming flow, or in the fixed metallic resistance silk thread of model specific position, in metallic resistance before experiment
Coat one layer of oil on silk thread, when experiment, which is powered, makes metallic resistance silk thread generate heat, and the heated smoke of oil and forms white smoke, smog
It can downstream be flowed away with air-flow, and then show flow regime.
