Fluid Dynamics = Fun (Just back from holiday!)

Just had a weeks activity holiday at Center Parcs here in the UK with my two boys, aged 13 and 16, so I’m now back at work for a well-earned rest!

We managed to cram in quite a lot – archery, tennis, racquetball, laser clay shooting, American pool, snooker, and kayaking, as well as a quad bike trek through the woods.

Center Parcs is set in 400 acres of forest with lots of very tame wildlife, like rabbits, squirrels and deer. The main attraction is a subtropical swimming paradise with outdoor wild-water rapids – a fast-moving dare-devil route which we went on most days. My eldest son (being a dare-devil) decided to stand up and ‘surf’ his way down one of the inclined shallow sections (it was difficult to get a photo, but see below).

The water flows in a thin laminar sheet over smooth painted stone before it meets the next deep pool where it becomes turbulent again, producing strong recirculations and undercurrents that make it hard to move unless you stand up. The amount of kinetic energy stored in the turbulent flow really is impressive. Fluid Dynamics = Fun.

About John Parry

John ParryI started my career in the consultancy group at CHAM Ltd., using PHOENICS for a variety of CFD applications. From the consultancy group I moved into support, helping customers debug models, and figuring out how to model new applications. That broadened into delivering training courses and creating training material. I was invited to join Flomerics when it started in 1989 to head up Customer Services, and I jumped at the chance to work for a startup. After a few years supporting customers using FloTHERM I moved across into research, developing thermofluid models of common electronic parts, like fans and IC packages, later managing the DELPHI and SEED projects. More recently I worked with Flomerics’ Finance Director on the acquisition of MicReD, helping to integrate MicReD’s business into Flomerics Group which was great fun. Since Flomerics acquired Nika, I’ve been responsible for promoting the FloEFD suite in education, and moved into marketing. I now work as part of the Mechanical Analysis Division’s Corporate Marketing group, responsible for ElectronicsCooling Magazine and the division’s Higher Education Program. Expertise: I’m a chemical engineer by training and did a PhD in reactor design before getting involved with CFD more than 25 years ago. Visit John Parry’s Blog
