In my previous blog post, “How the Design of a Wind Turbine Differs from other Types of Turbines”, I showed that the very small pressure drop across the rotor makes wind turbine design different from...
Wind power generation is rapidly growing worldwide, and with that growth, demand for wind turbine design engineers is also growing. However, an engineer who has experience designing turbines in most...
Space launch vehicles can exhibit self-excited longitudinal oscillations, also known as “Pogo” — so named because the phenomenon vibrates the rocket up and down in a manner similar to bouncing on a...
The recent success of Rocket Lab, putting small satellites into orbit with its Electron rocket, is a significant milestone in the evolution of space flight. The Electron rocket is powered by a set of...
Cavitation occurs in a pump when the bulk liquid pressure starts to approach the vapor pressure of the liquid, and cavities of vapor form as seen in Figure 1. This figure shows the inlet of a...
