This paper concerns the application of a long short-term memory model (LSTM) for high-resolution reconstruction of turbulent pressure fluctuation signals from sparse (reduced) data. The model’s training was performed using data from high-resolution

Experimental and computational data and field data obtained from measurements are often sparse and noisy. Consequently, interpolating unknown functions under these restrictions to provide accurate predictions is very challenging. This study compares

This paper concerns indoor explosions and the impact of blasts on humans. The standard approach from the engineering and medical communities is that blast overpressure is the criterion that determines trauma and injury. However, this study shows that

This paper presents a study of high speed boundary layers using the wavelet method. We analyze direct numerical simulation data for high-speed, compressible transitional, and turbulent boundary layer flows using orthogonal anisotropic wavelets. The w

This study investigates the nuclear blast effects on humans inside a building within a moderate damage zone. These effects depend on many parameters that must be better understood. In addition, the nuclear blast effects will spread further away than

We address the impact of rocket exhaust gases on atmospheric pollution through high-resolution computational fluid dynamics simulations. We have modeled the exhaust gases and developing plume at several altitudes along a typical trajectory of a stand
