This article provides an overview of how computational fluid dynamics (CFD) works, and what benefits it can bring to the chemical process industries Sustainability, waste reduction, energy efficiency and increased demand for engineered material are driving process engineers to continuously…
Portable laptop computers and smartphones can be used to emulate computational fluid dynamics (CFD) modeling results using this interpolation procedure Most engineers are familiar with computational-fluid-dynamics (CFD) models and their power (for an overview of CFD, see Part 1). At…
This practical overview of ASTM standards can serve as a roadmap when selecting and evaluating heat transfer fluids Heat-transfer-fluid systems are often used for process heating to 500°F or higher. To accomplish heating above 500°F, steam pressure must be above…
Working with supercritical fluids poses challenges when designing heat exchangers. Some practical tips and precautions are presented here Industrial applications involving fluids at high pressure — pressure above the critical pressure of a particular fluid — are increasing in number.…
