Overview of sensors suitable for active flow control methods [PDF]
, 2015 Hlavným cieľom tejto bakalárskej práce bolo vytvorenie prehľadu vyvíjaných a už aplikovaných senzorov pre účely aktívneho riadenia prúdov. Senzory musia splňovať niektoré podmienky, preto výber senzorov bol naviazaný na reálnych výsledkoch testovacích ...

Experimental Study of an Acoustically Excited Plane Jet at Low Reynolds Numbers
Journal of Applied Fluid Mechanics, 2019 The dynamics of a vertical two-dimensional air jet under acoustic excitations at a low Reynolds number are investigated experimentally. The perturbation is introduced by means of a loudspeaker located in a settling chamber before the nozzle exit.

A calibration technique for a hot-wire-probe vector anemometer [PDF]
Calibration tests using hot wires were conducted using a newly developed test rig that greatly reduced the data acquisition time. A comparison of measured and computed velocity vector magnitude and direction indicates the necessity of complete probe ...

Impact of new instrumentation on advanced turbine research [PDF]
A description is presented of an orderly test program that progresses from the simplest stationary geometry to the more complex, three dimensional, rotating turbine stage. The instrumentation requirements for this evolution of testing are described.

Extended Applications of the Hot-Wire Anemometer
Review of Scientific Instruments, 1947 The use of the hot-wire anemometer has been extended to include the measurement of temperature fluctuation level as well as temperature-velocity correlation, in a turbulent flow with heat transfer. Secondly, the hot wire can be used for the determination of mean relative concentration in the mixing of two gases of different known thermal

A wind model for an elevated STOL-port configuration [PDF]
Measurements of mean velocity magnitude and direction as well as three-dimensional turbulence intensity were made in the flow over a model of an elevated STOL-port. A 1:300 scale model was placed in a wind tunnel flow simulating the mean velocity profile

An experimental study of a self-confined flow with ring-vorticity distribution [PDF]
A new form of self-confined flow was investigated in which a recirculation zone forms away from any solid boundary. An inviscid flow analysis indicated that in a purely meridional axisymmetric flow a stationary, spherical, self-confined region should ...
