The main focus of this study is to apply a computational tool for the flow analysis of the turbine engine that has been tested with ice crystal ingestion in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center. The PSL has been used to test a highly instrumented Honeywell ALF502R-5A (LF11) turbofan engine at simulated altitude operating conditions. Test data analysis with an en...
Recently, a novel environmental stress index (ESI) which is composed from commonly used meteorological variables: ambient temperature (T(a)), relative humidity (RH), and solar radiation (SR) was suggested as follows: ESI = 0.63T(a)-0.03RH+0.002SR+0.0054(T(a) x RH)-0.073(0.1+SR)(-1); (degrees C) The purpose of the present study was to evaluate and validate the ESI for hot dry and hot wet climati...
This paper is a review of wet and dry etching of one of the most common types of glass: Pyrex. The paper analyzes the methods for increasing the glass etch rate in HF solutions, namely, annealing, concentration, ultrasonic agitation and temperature. The limitations of the wet etching of glass are also presented. Mashing layers commonly used for deep wet etching of glass are analyzed, in terms o...
