FORTRAN program to generate engine inlet flow contour maps and distortion parameters

Comparison of engine/inlet distortion measurements with MEMS and ESP pressure sensors

A study of active-flow control in a small-scale boundary layer ingestion inlet was conducted at the NASA Langley Basic Aerodynamic Research Tunnel (BART). Forty MEMS pressure sensors, in a rake style configuration, were used to examine both the mean (DC) and high frequency (AC) components of the total pressure across the inlet/engine interface plane. The mean component was acquired and used to ...

Distortion of Flow Measurement and Cavitation Occurs Due to Orifice Inlet Velocity Profiles

This analysis investigates the distortion of flow measurement and the increase of cavitation along orifice flowmeter. The analysis using the numerical method (CFD) validated the distortion of flow measurement through the inlet velocity profile considering the convergence and grid dependency. Realizable k-e model was selected and y+ was about 50 in this numerical analysis. This analysis also est...

Experience Compiling Fortran to Program Dependence Graphs

The program dependence graph (PDG) is being used in research projects for compilation to parallel architectures, program version integration and program semantics. This paper describes the methods used in a prototype Fortran-to-PDG translator called the PDG Testbed. Implementation decisions and details of the PDG Testbed project are described as a complement to the formal papers detailing the a...

Using Computers to Individually-generate vs. Collaboratively-generate Concept Maps

Five eighth grade science classes of students in at a middle school were assigned to three treatment groups: those who individually concept mapped, those who collaboratively concept mapped, and those who independently used their study time. The findings revealed that individually generating concept maps on computers during study time positively influenced science concept learning above and beyo...
