Cloud computing has the potential to permit scientists to scale up to solve large science problems without having to invest in hardware and software infrastructure. Even though its use has become commonplace in the business realm, its use in HPC is still limited to a few applications. This project aims at developing, prototyping, validating, and commercializing the world's first cloud-enabled ...

Diffractive waveplates are optical components made of thin films of anisotropic materials by modulating their optical axis orientation in the plane of the waveplate. The family of diffractive waveplates wherein this modulation is axially symmetricÂ? vector vortex waveplates (VVWs) Â? impart a spiral phase modulation at a light beam propagated through the waveplate. As a result, the intensity of ...

AN ANALYTICAL MODEL AND A COMPUTER CODE FOR THE DETAILED SIMULATION OF THREE-PHASE FLOWS IN LIQUID ROCKET THRUST CHAMBERS IS PROPOSED. THE MODEL DESCRIBES BEHAVIOR OF THE LIQUID, DISPERSED AND GASEOUS PHASES IN A MOST EFFICIENT FORM. THE CONTINOUS GAS-PHASE FLOW AND COMBUSTION ARE DESCRIBED IN EULERIAN COORDINATES; THE SPRAY FLOW, DROPLET EVAPORATION AND COMBUSTION PROCESSES ARE SIMULATED IN A GRI ...

Advanced Materials Technology, Inc (AMTI) responds to the NASA solicitation X10 "Cryogenic Propellant Storage and Transfer" under subtopic X.01 "Cryogenic Fluid Management Technologies". NASA is seeking for technologies in advanced cryogenic fluid storage and transfer to reduce launch operation costs by providing higher efficiency, lower maintenance and longer life while improving safety and mini ...

The innovation proposed here is a high performance, high fidelity simulation capability to enable accurate, fast and robust simulation of unsteady turbulent, reacting flows involving propellants of relevance to NASA (GOX/GH2, LOX/LH2 and LOX/LCH4). The key features of this proposed capability are: (a) Hybrid RANS-LES (HRLES) methodology, and (b) flamelet modeling for turbulent combustion, incorpo ...

THIS EFFORT WILL ENHANCE THE CAPABILITY OF THE AIR FORCE PARABOLIZED NAVIER STOKES CODE (AFWAL PNS CODE) TO PREDICT SKIN FRICTION AND HEAT TRANSFER TO HIGH SPEED FLIGHT VEHICLES. THE CURRENT PREDICTION TECHNIQUES REQUIRE EXTREMELY ACCURATE CALCULATIONS OF VELOCITY AND TEMPERATURE IN THE VICINITY OF THE WALL. THE EFFORT HERE WILL REPLACE THIS PROCEDURE BY USING INTEGRAL MOMENTUM AND ENERGY EQUATION ...
