This study seeks to deepen our understanding of heat transmission and fluid dynamics within a cross-flow microchannel heat exchanger (CFMCHE). Jan 10, 2024 ... This study demonstrates that small-scale differences in stream conditions within oil palm can influence semi-aquatic bugs. Structures fail when a part breaks or is permanently disturbed in some way. This can happen because the forces on the structure become too great for it to bear.
