Abstract: The solution for the torsional-stress problem in a small-angle helical coil of rectangular cross section is derived. The exact solution is then approximated for validity at small coil indices. ...

Abstract: Studies making use of higher vibration modes and frequencies have indicated a need for a more accurate beam theory. Equations of motion are developed here that give a more accurate representation ...

Abstract: The different airflow regimes for prototype orographic problems are controlled by a reduced set of nondimensional numbers. A regime diagram is deduced for the Long problem from a set of numerical simulations made with a ...

Abstract: The aim of this article is to summarize some of the results of a study of a driver’s seat with an electro-pneumatic active suspension utilizing a pneumatic spring and a proportional ...

Abstract: In vaned diffusers of centrifugal compressors many different flow phenomena interfere with one another, and different geometric parameters influence the flow field. Variations of these parameters ...

Abstract: The purpose of this study was to investigate the characteristics of flow in a symmetrically branched tube that had an area ratio (0.8) and angle of branching (70 deg) that were comparable ...

Abstract: A simple method is developed for computing the interactions among various factors influencing the atmospheric circulations. It is shown how numerical simulations can be utilized to obtain the pure contribution of any factor ...
