Pitot-Pressure Measurements in Flow Fields Behind a Rectangular Nozzle with Exhaust Jet for Free-Stream Mach Numbers of 0.00, 0.60, and 1.20 [PDF]

An investigation has been conducted in the Langley 16-Foot Transonic Tunnel to measure the flow field in and around the jet exhaust from a nonaxisymmetric nozzle configuration. The nozzle had a rectangular exit with a width-to-height ratio of 2.38. Pitot-

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

Advanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.

Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

Advanced Materials, EarlyView.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Direct Numerical Simulation of Acoustic Disturbances in the Rectangular Test Section of a Hypersonic Wind Tunnel [PDF]

Direct numerical simulations (DNS) of the full-scale rectangular nozzle of a hypersonic wind tunnel are conducted to study the acoustic freestream fluctuations radiating from turbulent boundary layers (TBLs) along the nozzle walls.
