Influences of Turbulence Characteristic on the Dispersion Behavior of Droplets in the Spray Flame

Journal of Thermal Science and Technology, 2008
The authors investigated the effect of the turbulence of an air current on droplet dispersion in a spray flame. Wire meshes of different mesh sizes were inserted behind a two-fluid type nozzle each time to vary the air current turbulence characteristics,

Cold Climate Wind: Challenges, Technological Solutions and Policy

WIREs Energy and Environment, Volume 15, Issue 1, March 2026.
Operating wind farms in cold climates creates unique challenges for turbine designers, owners, and operators. Solving these challenges requires specific technological and policy solutions at all levels. ABSTRACT Cold‐climate wind power represents a major subset of onshore global capacity, with approximately one third of existing installations located ...

Laminar Turbulent Transition in a Boundary Layer Subjected to Weak Free Stream Turbulence

Journal of Fluid Science and Technology, 2008
For revealing the transition process in a flat plate boundary layer subjected to a weak free stream turbulence, flow visualization and hot-wire measurements were performed. A weak free stream turbulence was generated by a turbulence grid mounted upstream

Characterising Spectral Sensitivity and the Role of Sunlight Intensity in Japanese Beetle (Popillia japonica) Surveillance and Monitoring (Coleoptera: Scarabaeidae)

Journal of Applied Entomology, Volume 150, Issue 1, Page 46-55, February 2026.
ABSTRACT The Japanese beetle (JB) Popillia japonica (Coleoptera: Scarabaeidae) has been a significant invasive pest for over a century in North America. Several studies have reported that plants under direct sunlight are preferred and trap colour affects the number of beetles captured, indicating that visual stimuli influence JB behaviour. Despite this,

Preschoolers' Scientific Curiosity and Inquiry Capabilities: An Ecological Research Approach

Journal of Research in Science Teaching, Volume 63, Issue 1, Page 40-61, January 2026.
ABSTRACT Existing tools for measuring scientific curiosity often fail to capture its multifaceted, dynamic nature—particularly in early childhood, where behaviors are context‐dependent, non‐verbal, and emergent. These challenges limit our ability to understand and support young children's scientific engagement.
