Water & Turbomachinery - Two Great Things, That Go Great Together

by Andrew Provo on Mar 22, 2019 10:17:34 AM

I work with water a lot here at Concepts NREC. Water is frequently the fluid that flows through various types of rotating equipment we design to either release or store energy. Mankind’s fascination with manipulating the movement of water goes way back; read Mark Anderson’s blog on  Early Water Handling to see just how far back it goes. Today, more advanced turbomachinery is used for both hydroelectric and hydrokinetic applications. 

Designing Ruled Surfaces for Flank Milling

by Peter Klein on Mar 15, 2019 10:21:00 AM

As discussed in my previous blog post, Flank Milling, How Hard Can it Be?, turbomachinery blades are commonly designed as ruled surfaces, with the goal of making manufacturing easier and faster with flank-milling.  While some non-ruled surfaces can be acceptably flank-milled, the programming and machining process for flank-milling is generally more dependable with ruled data. However, the ruled data should be well conditioned, and several pitfalls should be avoided during the design and construction process.

What's Better than Perfect? Semi-Perfect Gas Models

by Mark R. Anderson on Mar 8, 2019 10:30:00 AM

In a previous blog, Fluid Phenomena Primer: Energy Versus Temperature, Specific HeatI explained the behavior for gas phase fluids and how the temperature is affected at high energy levels.  In another blog, When Perfect is Good Enough - Perfect Gas Models, we looked at the simple perfect gas model.  In this blog, we’ll explore the next step up in the hierarchy of gas thermodynamic modeling: semi-perfect gas.

How the Design of a Wind Turbine Differs from Other Types

by Kerry Oliphant on Mar 1, 2019 10:22:00 AM

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 applications, will often have trouble translating their hard-won skills for general turbine design, into the wind turbine design. Why?
