Spray Diagnostics Measurements of an air blast atomizer at ambient pressure conditions are presented. The atomizer was developed by United Technologies Aerospace Systems as part of a combustor design for NASA's Environmentally Responsible Aviation (ERA) N+2 advanced, low NOx combustor technologies program. The goals of this combustor design is to meet or exceed the N+2 LTO NOx goal of 75% reduc...

Production forecasting plays an important role in development plans during the entire period of petroleum exploration and development. Artificial intelligence has been extensively investigated recent years because its capacity to analyze interpret complex data. With emergence spatiotemporal models that can integrate graph convolutional networks (GCN) recurrent neural (RNN), it is now possible a...
