Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

High Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Parametric and nonparametric identification of shell and tube heat exchanger mathematical model [PDF]

, 2012
Parametric and nonparametric models of a shell and tube heat exchanger are studied. Such models are very important because they provide information about controlling a system operation. Without the model, the control task would be difficult for tuning

Series Connection of LCC and Full Bridge MMC With DC Fault Ride‐Through Capability for Lightweight HVDC Transmission

Engineering Reports, Volume 8, Issue 4, April 2026.
In this work, we investigate a lightweight HVDC converter topology that combines the strengths of line‐commutated converters (LCC) and full‐bridge modular multilevel converters (MMC) to address the high cost and large footprint of conventional HVDC stations.

The Reaction‐to‐Fire Performance of Intumescent Coating After Ageing by Thermal and Moisture Exposure

Fire and Materials, Volume 50, Issue 3, Page 318-333, April 2026.
ABSTRACT Materials and products age with time and their properties change. It is known that, for example, the mechanical strength may be deteriorated from ageing. To understand the ageing effect on the fire behaviour of materials and products is important to maintain the safety level of the construction or application.
