A Review of Flow Field and Heat Transfer Characteristics of Jet Impingement From Special‐Shaped Holes

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
Special‐shaped nozzles and nanofluid integration enhance jet impingement cooling by improving heat transfer and thermal uniformity. However, gains are constrained by increased pressure drop and stability challenges, highlighting the need for optimized designs and multiscale modeling to achieve efficient, scalable thermal management.

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2880-2896, September 2026.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.
