Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Study of Electrical Parameter Calculation for Traction Network in Single-line Tunnel Based on the Extend of Carson Theory

Kongzhi Yu Xinxi Jishu, 2016
Carson theory assumes that all conductors on the earth take the ground as an unique loop circuit, but there are multiple return paths in one actual traction network, thus it is difficult to directly determine current distribution and obtain the current ...

Accounting power supply schemes for traction substations in the calculation of short circuits in the AC traction network

Vestnik of the Railway Research Institute, 2019
When calculating short-circuit currents in the AC traction network, it is assumed that each of the traction substations receives power from uncoupled external power supply sources with known resistances. In some cases, especially when powering a group of traction substations from a high-voltage power line of a longitudinal power supply, the external ...
