R. E. O'Malley, Jr. A basic problem in singular perturabations is to study systems of differential equations whose order is reduced when a small parameter becomes zero. It is important for numerous ...

The state and properties of boundary layer (BL) flows are very important issues for the design and operation of high performance air- and ground- vehicles as well as for many industrial flow ...

Improving forecasting for a host of severe weather events may be possible thanks to a more comprehensive method for measuring the Earth's boundary layer depth, developed by Penn State researchers. The ...

The results of theory/experiment correlative studies at subsonic and supersonic Mach numbers are presented in this paper. These studies were conducted by using theoretical design tools consisting of ...
