Dynalysis of Princeton is a small but vigorous research organization started in 1968 and incorporated under the laws of the State of New Jersey. Dynalysis was formed to carry out basic but innovative scientific research and apply the results to the solution of practical environmental and engineering problems. Since advanced technology is applied by those who developed it, there is no publication time lag or technical communications gap. Basic research is conducted is such areas as turbulence modelling, numerical analysis, heat transfer and fluid flows. With this broad foundation, sophisticated prediction methods are developed for applications in areas such as oceanic and atmospheric circulation, and aerodynamics and heat transfer in turbomachinery. Over the years considerable expertise has been built up in these areas, both by basic research into fundamental processes and by construction of numerical models to solve a variety of problems in these fields. Dynalysis scientists are always prepared to meet the challenge of applying their broad experience to the solution of practical problems by development of state-of- the-art analytical, numerical and experimental techniques.
