The skin of fast-swimming sharks is proposed to have mechanisms to reduce drag and delay flow separation. The shortfin mako Isurus oxyrinchus is one of the fastest and most agile ocean predators and would benefit from minimizing its pressure drag by controlling flow separation. …
Synthetic jet actuators have previously been defined as having potential use in both internal and external aerodynamic applications. The formation of a jet flow perpendicular to the surface of an aerofoil or in a duct of diffuser has a range of potential flow control benefits. T…
Plasma actuators are electrical devices that generate a wall bounded jet without the use of any moving parts. For aerodynamic applications they can be used as flow control devices to delay separation and augment lift on a wing. The aim of this project is to initially develop a s…
There is currently growing interest in the field of Micro Air Vehicles (MAVs). A MAV is characterized by its low Reynolds numbers flight regime which makes lift and thrust creation a significant challenge. One possible solution inspired by nature is flapping flight, but instead …
Titreşim ve gürültü problemleri her zaman mühendisler için zorlu bir uğraş olmuştur. Mühendisler hala bu sorunlara çözüm bulmaya devam ediyorlar. Gemicilikte ve enerji üretiminde kullanılan büyük dizel motorları için de çözülmeyi bekleyen pek çok titreşim sorunu var. Bu çalışman…
Wind storms pose dangerous threats to human lives and are an enormous drain on the economy. Their damage to buildings usually starts with the failure of structural components that are subjected to excessive wind loads. In this dissertation, we investigate the characteristics of …
