Anti-bacterial activity of lysozyme in pitching yeast and effect of lysozyme on yeast fermentation [PDF]
, 2009 Lysozyme has antibacterial activity against Gram-positive bacteria and has no activity against yeast. As such, lysozyme can be used for the specific inhibition of beer spoilage bacteria.

A new stall-onset criterion for low speed dynamic-stall [PDF]
, 2005 The Beddoes/Leishman dynamic-stall model has become one of the most popular for the provision of unsteady aerofoil data embedded in much larger codes.

A vortex-filament and core model for wings with edge vortex separation [PDF]
A vortex filament-vortex core method for predicting aerodynamic characteristics of slender wings with edge vortex separation was developed. Semi-empirical but simple methods were used to determine the initial positions of the free sheet and vortex core ...

Genetic Algorithm Based Optimization of Wing Rotation in Hover
Fluids, 2018 The pitching kinematics of an experimental hovering flapping wing setup are optimized by means of a genetic algorithm. The pitching kinematics of the setup are parameterized with seven degrees of freedom to allow for complex non-linear and non-harmonic ...

Scaling the propulsive performance of heaving and pitching foils
, 2017 Scaling laws for the propulsive performance of rigid foils undergoing oscillatory heaving and pitching motions are presented. Water tunnel experiments on a nominally two-dimensional flow validate the scaling laws, with the scaled data for thrust, power ...
