Abstract: AbstractThe global dissipation caused by bottom boundary layer drag is one of the major pathways for the consumption of kinetic energy in the deep ocean. However, the spatial distribution and global integral of the drag ...

Abstract: The feasibility of laser direct welding quad flat pack (QFP) device without solder is analyzed and practiced. The relations between the tensile strength of QFP joints and laser welding parameters are investigated, and the ...

Abstract: High-power permanent magnet synchronous motors (HPMSM) face extremely harsh cooling conditions due to their high power and complex structure. An efficient cooling system is pivotal to ensuring the safety and operational ...
