“…While active transducers, such as piezoresistive element and piezoelectric element, are based on the direct measurement of the pressure, passive ones, including stain gauges and variable reluctance, rely on indirect measurement of the pressure through detecting deformation of a membrane under pressure force. 28 The measurement domain of common types of active and passive transducers is compared in Fig. 2.…”

“…Copyright 2020 Springer Nature. 28 Forces and moments acting on a test piece in the wind tunnel are important parameters, which are typically measured by multi-component (one to six) balances. A six-component balance is capable of measuring three force components of lift, drag, and side, and three moment components…”

“…Pressure probes, namely Pitot tube and Prandtl tube which are used for measurement of total and static pressures, respectively, can be indirectly employed for the determination of the flow velocity in the wind tunnel. 28 Although this technique is intrusive, it benefits from simplicity and low cost. 26 In applications with three-dimensional flows or an unknown incoming flow angle such as the swirling flow, more sophisticated types of pressure-based velocity measurement methods, e.g., multi-hole cobra probes, can be implemented.…”

Experimental studies dealing with the wake of isolated stationary bluff-bodies are reviewed. After briefly recalling the pioneering works in this domain, the paper focuses on recent research conducted with the latest experimental methods and techniques. The review encompasses a range of topics, including, the effects of bluff-body geometry (non-circular cross sections and nonuniformity in spanwise direction), steady and unsteady (periodic and non-periodic) inflow conditions; surface proximity (rigid wall, confinement and water free surface) and non-Newtonian fluids. Focus is brought to the flow physics of the wakes, including especially the complex threedimensional and oscillatory behaviours induced by the periodic vortex shedding phenomenon. The paper aims to offer a critical and systematic review of new knowledge and findings on the subject area, as well as emerging? and the most frequently adopted experimental techniques. The review also helps identifying knowledge gaps in the literature that need to be addressed in future investigations.

This chapter is devoted to the aerodynamic evaluation to experimentally investigate first the flow structure and the morphing effects on the tRS (transonic Reduced Scale) prototype of 15 cm chord, and secondly to evaluate the impact of the optimal morphing cambering on the LS (Large Scale) prototype in respect of the aerodynamic performance increase. The first part concerning the transonic regimes involves morphing through optimal trailing edge region vibration performed in the wind tunnel of IMP-PAN concerning cruise phase conditions and the second investigates the aerodynamic perfomance through cambering of the high lift flap of 1 m chord and 2 m span, emebedded in the fixed wing configuration of 4 m span in the POLIMI's wind tunnel in take-off and landing conditions.
