Stokes problems are a set of differential equations that describe fluid motion in flows with low Reynolds numberBurada bahsedilen düşük Reynolds sayıları birin çok daha altındaki değerlerdir. ">【1】, where viscous forces dominate. These equations play a fundamental role in applications such as microfluidics biological systems and flows around slowly moving objects. Stokes problems represent special cases derived from the Navier-Stokes equationsFransız mühendis ve fizikçi Claude-Louis Navier ve

Thermal air currents (thermals) are a natural phenomenon that enables birds, gliders, and even unmanned aerial vehicles (UAVs) to remain airborne and cover long distances without additional engine power. While soaring flight conserves energy, achieving very long distances solely through soaring is a significant challenge for both birds and humans; the solution lies in utilizing thermal air currents—columns of warm air rising faster than the descent rate of birds or gliders, heated by the Sun in

To understand how aircraft move through the air, it is necessary to first examine the effects of physical forces. An aircraft’s ability to remain airborne and maneuver depends on the interaction of four fundamental forces: lift, weight, thrust, and drag. Among these, thrust and lift are critically important for takeoff and sustained flight.
