Engineers: Stress and Pressure at Work

Engineers have a tough life. I mean what other profession has to deal with stress, pressure and strain? It sounds like engineers have a lot in common with mental health professionals. If you are a fluids engineer like I am, then strain itself is not enough. What matters is how fast the strain happens (the rate of strain). This affects the viscosity...

Reaching Equilibrium: System Energy Balance in AFT Fathom and AFT Arrow

AFT Fathom and AFT Arrow both have the powerful ability to model heat transfer in pipes and heat exchangers , allowing you to represent these critical features of temperature-sensitive systems in your hydraulic model. However, without being able to see the affect heat transfer has on an entire system these features would be of limited usefulness. One of the most powerful aspects of AFT’s implementation of heat transfer is that energy is balanced across the entire system. For example, you can observe changes in pump or control valve operation when adding heat transfer to a remote part of a system. Looking...

It’s the Economy, Stupid. Or Is It?

A few months ago I attended a CEO forum in Colorado where a big topic on the minds of the 1000 CEOs in attendance was the state and direction of the US and global economy. The keynote speaker Brian Beaulieu began his presentation with this assessment of the economy from TIME magazine: The U.S. economy remains almost comatose. The current slump already ranks as the longest period of sustained weakness since the Great Depression. Once-in-a-lifetime dislocations will take years to work out.  Among them: the job drought, the debt hangover, the defense-industry contraction, the banking collapse, the real estate depression, the health-care...
