In this paper, the effect of rotor speed and boundary layer on the broadband noise from wind turbines are discussed. The results from the computations have been validated using the far field acoustic measurements from a similar sized turbine
Trailing edge noise prediction from NACA 0012 and NACA 6320 using empirical p...vasishta bhargava
Trailing edge of airfoil represents one of important sources in aerodynamic noise production. In this paper, the numerical computation of sound pressure using quasi empirical model and wall pressure spectrum models based on external pressure gradients was conducted for NACA 0012 and NACA 6320 airfoils. The development of boundary layer thickness and displacement thickness for different chord lengths and Mach numbers with varying angles of attack, are illustrated for NACA 0012. The sound pressure levels evaluated between 00 to 60angles of attack and at constant chord length of 1.2m using BPM model showed change of ~5dB in peak amplitude. The maximum test velocity and chord length used for analysis is 65 m/s and 1.5m. The relative velocities for airfoils have been computed using the boundary element and panel method. Boundary layer properties involving chord Reynolds number, 3.14 x106, 4.6 x106and Reynolds number based on wall shear, 7410, 6865 were assessed at 20 AOA for NACA 0012. Results have found higher values for thickness at increasing angle of attack but decayed along chord length. Comparison of wall pressure spectrum for favorable and adverse pressure gradients were done and validated with existing literature predictions

Prediction of aerodynamic characteristics for slender bluff bodies with nose ...vasishta bhargava
the numerical approach is used to verify the aero/hydrodynamic performance of different
geometries of nose cones. Computational methods predict the flow characteristics fairly accurately in order to validate
the data obtained from experiments. The simulation involves muzzle velocity that range from 5m/s to 25 m/s i.e. 1.69 to
8.4 x 105
and calculated for the different angle of attack, -10 to 20 degrees, to demonstrate the flow behavior around the
shells. Nosecone is the most forward section of any slender moving bodies which are used in rockets, guided missiles,
submarines, aircraft drop tanks and aircraft fuselage to reduce the aerodynamic or hydrodynamic drag. The basic
geometry of bluff body is cylinder with variant nosecone shapes such as flat and tapered head, with moderate to low
taper ratios and conical head.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
