Experimental study of the aerodynamic noise radiated by cylinders with different cross-sections and yaw angles
Vortex shedding from cylinders has been extensively studied due to its occurrence in many engineering fields. Many experimental studies reported in the literature focus on the aerodynamics of the vortex shedding process but the literature about the radiated noise is more scarce. The aim of the work presented here is to extend the available noise data. Aero-acoustic wind tunnel tests were carrie...
متن کاملInterference of Wind Turbines with Different Yaw Angles of the Upstream Wind Turbine
This experimental study was conducted in a wind tunnel using two turbines in tandem arrangement and downstream turbine is located at X/D=2. The purpose was to investigate how yawing the upstream turbine will affect the performance of the downstream turbine as well as the upstream turbine. Wind loading (thrust force), rotational frequency and power output are the parameters used to define the pe...
متن کاملMicro Coriolis Flow Sensor
In recent years, the interest in integrated microfluidic systems has been steadily growing. In these systems (for instance (bio)chemical and DNA analysis and synthesis devices), accurate dosing of liquids and/or gases is of great importance. To achieve this, accurate (mass) flow sensing is necessary. This project is dedicated to the development of a new micro Coriolis flow sensor. The inherent ...
متن کاملWaves, Coriolis Force and the Dynamo Effect
Dynamo activity caused by waves in a rotating magneto-plasma is investigated. In astrophysical environments such as accretion disks and at sufficiently small spatial scales, the Hall effect is likely to play an important role. It is shown that a combination of the Coriolis force and Hall effect can produce a finite α-effect by generating net helicity in the small scales. The shear/ion-cyclotron...
متن کاملRobust Yaw Damping of Cars withFront and
For a linear model of active car steering a robust decoupling control law by feedback of the yaw rate to front wheel steering was derived earlier. In the present paper this control law is extended by feedback of the yaw rate to rear wheel steering. A controller structure with one free damping parameter k D is derived with the following properties: i) Damping and natural frequency of the yaw mod...
