The purpose of this paper is to discuss and clarify the explanations commonly cited for the aerodynamic lift generated by a wing, and to then analyse, as a case study of engineering discovery, the aerodynamic revolutions which have taken place within Formula 1 in the past 40 years. The paper begins with an introduction that provides a succinct summary of the mathematics of fluid mechanics.

The influence of anemometer rotor shape parameters, such as the cups' front area or their center rotation radius on the anemometer's performance was analyzed. This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors. The results we...

Abstract. The Direct Simulation Monte-Carlo (DSMC) technique is used for numerical analysis of rarefied-gas hypersonic flows near a blunt plate, wedge, two side-by-side plates, disk, torus, and rotating cylinder. The role of various similarity parameters (Knudsen and Mach numbers, geometrical and temperature factors, specific heat ratios, and others) in aerodynamics of the probes is studied. Im...

Abstract: Aerodynamics and motion performance of the floating vertical wind turbine (VAWT) were studied in this paper, where the wind turbine was H-type and the floating foundation was truss spar type. Based on the double-multiple-stream-tube theory, the formulae were deduced to calculate the aerodynamic loads acting on the wind turbine considering the motions of the floating foundation. The su...

This thesis studies ways of broadening the range of a piezoelectric flow induced vibration harvester. The proposed device consists of a flap connected with a hinge to a spring. Existing harvesters are designed to replace or charge batteries for low power systems in the range of milliwatts. These systems produce low amounts of power, but for low flow speeds. The objective of this thesis is to in...

We consider the aerodynamics of football, specifically, interaction between a ball in flight and ambient air. Doing so allows one to account for characteristic range trajectories balls flight, as well their anomalous deflections may be induced by striking either with or without spin. The dynamics viscous boundary layers is briefly reviewed, its critical importance on highlighted. Magnus effect ...
