Scarano, F. (author), Ghaemi, S. (author), Alp Caridi, G.C. (author), Bosbach, J. (author), Dierksheide, U. (author), Sciacchitano, A. (author)The flow-tracing fidelity of sub-millimetre diameter helium-filled soap bubbles (HFSB) for low-speed aerodynamics is studied. The main interest of using HFSB in relation to micron-size droplets is the large amount of scattered light, enabling larger-scale three-dimensional experiments by tomographic PIV. The assessment of aerodynamic behaviour...journal article 2015

Kotsonis, M. (author), Ghaemi, S. (author)The forcing behavior of a dielectric barrier discharge (DBD) actuator is investigated experimentally using a time-resolved particle image velocimetry (PIV) system in conjunction with a phase shifting technique. The spatio-temporal evolution of the induced flowfield is accurately captured within one high voltage (HV) cycle allowing the...journal article 2011

Kotsonis, M. (author), Ghaemi, S. (author), Veldhuis, L. (author), Scanorano, F. (author)A novel technique is proposed and investigated for the estimation of the body force field resulting from the operation of a dielectric barrier discharge plasma actuator. The technique relies on the measurement of the spatio-temporal evolution of the induced velocity field using high-speed particle image velocimetry (PIV). The technique has the...journal article 2011

Kotsonis, M. (author), Ghaemi, S. (author), Giepman, R.H.M. (author), Veldhuis, L.L.M. (author)An experimental investigation on thrust and body force of Dielectric Barrier Discharge (DBD) /plasma actuators aimed at low power flow control applications is presented. A parametric study on thrust is conducted for a wide range of geometrical configurations as well as several electrical operational conditions. Direct measurements of the induced...conference paper 2010
