Hydrodynamics of Pumps by Christopher E. Brennen was first published in 1994. Aside from my long-time professional acquaintance with the author, what caught my attention in this book are the various technical passages related to rocket propulsion turbomachines, including the Space Shuttle Main Engine. Over the years I would hear about the technical issues with these [...]
The stator section of a centrifugal pump, after flow exits the impeller, is usually either a ‘diffuser’ or a ‘volute’. The purpose of each of these two stator types is to efficiently diffuse velocity energy into pressure. Diffusers are characterized by a plurality of radially symmetric diffusing passageways surrounding the impeller. Either a volute-shaped or [...]
Years ago I owned a copy of Pump Handbook 1st Edition, by Karassik, Krutzsch, Fraser, and Messina. While it was a book to have on the shelf, it was not my primary source of pump engineering reference material. I obtained most of my pump technical information from other books and publications. Eventually someone “borrowed” my [...]

Any Westerner’s experience with Korea inevitably starts with the food. Yes, most have heard of kimchee and Korean BBQ. But until you’ve had a traditional Korean-style [...]
