THE RESEARCH IS BASED ON A NOVEL CONCEPT OF FLOW ANALYSIS, WHICH POSTULATES THAT THE LINEAR CONSTANT MONOTONOUS FLOW RATE AS NOW GENERALLY ADOPTED IN ALL TYPES OF FLOW ANALYSIS, CAN BE REPLACED BY A FLOW PATTERN, AS LONG AS THIS FLOW PATTERN CAN BE MAINTAINED AND STRICTLY REPRODUCED FROM ONE ANALYSIS CYCLE TO THE NEXT. THIS IN TURN ALLOWS USE OF A SINUSOIDAL FLOW, GENERATED BY A PAIRED SYRINGE PUM ...

SEVERAL AEROSPACE VECHICLES ARE CURRENTLY BEING CONSIDERED THAT HAVE A SIGNIFICANT PORTION OF THEIR FLIGHT PATH IN THE UPPER REACHES OF THE ATMOSPHERE. THE FLOW ABOUT THESE VEHICLES IS IN THE CONTINUUM-TRANSITION REGIME WHERE THE STANDARD EQUATIONS OF CONTINUUM FLOW, THE NAVIER-STOKES EQUATIONS, BEGIN TO FALL. THIS PROJECT WILL MODIFY THE HANA CODE, AN EXISTING NAVIER-STOKES CODE FOR THE ANALYSIS ...

ADVANCED SHORT TAKEOFF/VERTICAL LANDING AIRCRAFT ARE DESIGNED TO USE EXHAUST JETS DIRECTLY TO INCREASE LIFT. BEING ABLE TO MODEL NUMERICALLY THE FLOW FIELDS INVOLVED IN THESE DESIGNS WOULD GREATLY IMPROVE THE DESIGN PROCESS. THIS PROJECT WILL DEVELOP A COST-EFFECTIVE FLOW ANALYSIS TOOL FOR MODELING POWERED-LIFT AIRCRAFT FLOW FIELDS. A KEY INGREDIENT IN THE DEVELOPMENT OF A PRACTICAL FLOW ANALYSIS ...

COMPUTATIONAL FLUID DYNAMICS (CFD) METHODS GENERATE VAST AMOUNTS OF NUMERICAL DATA THAT MUST BE DISPLAYED GRAPHICALLYFOR USE. CURRENT GRAPHICAL COMPUTER SOFTWARE PROGRAMS CAN DISPLAY DATA ONLY ON LINES OR ON SURFACES DEFINED IN THE COMPUTATIONAL GRID. CFD SOFTWARE USERS DESIRE TO DISPLAY CFD DATA ON ARBITRARY SURFACES THAT MAY NOT CONFORM WITH THE COMPUTATIONAL GRID. A SOFTWARE PROGRAM WILL BE DEV ...

ASTROPOWER PROPOSES TO DEVELOP A LARGE-SCALE, HIGH-THROUGHPUT LIQUID PHASE EPITAXIAL (LPE) REACTOR FOR THEFABRICATION OF MULTI-LAYER III-V SEMICONDUCTOR DEVICES. A DESIGN GOAL OF 1000 CM(2) PER HOUR HAS BEEN ESTABLISHED WHILE MAINTAINING THE KEY FEATURES OF LPE: 1) HIGHEST MATERIAL QUALITY OF ALL EPITAXIAL GROWTH PROCESSES, 2) SIMPLICITY AND SAFETY (AS COMPARED TO MOCVD AND MBE), AND 3) LOW COST ( ...

CONFORMAL VAPOR PHASE EPITAXY (CVPE) IS A NEW TECHNIQUE FOR TWO-DIMENSIONAL CONSTRAINED GROWTH OF THIN SEMICONDUCTOR FILMS USING A HALIDE VAPOR TRANSPORT PROCESS. THIS TECHNIQUE WILL BE APPLIED TO THE GROWTH OF GAAS AND INP FILMS ON SILICON AND SAPPHIRE SUBSTRATES. EPITAXIAL-LATERALOVERGROWTH WITH HIGH ASPECT RATIOS IS ACHIEVED BY CONFINING GROWTH TO A THIN VOID SPACE BOUNDED BY AN OXIDE-MASK COAT ...
