Ingestion and deposition of fine particles on the surface coolant passage degrade blade’s cooling performance. This paper proposes a model to investigate complex characteristics during repeated collision, adhesion, rebound, removal events in small space inside typical impingement-effusion structure with double-wall blade. The results show that rarely collide wall escape directly from film hole ...

Body patterning behavior in unshelled cephalopod molluscs such as squid, octopuses, and cuttlefish is the ability of these animals to create complex patterns on their skin. This behavior is generated primarily by chromatophores, pigment-containing organs that are directly innervated by central motoneurons. The present study focuses on innervation patterns and location of chromatophore motoneuro...

In this paper, an experimental study investigating the effect of geometrical shape circular and rectangular pin fins on heat transfer performance boiling phenomenon is presented. A pool experiment in HFE-7100 dielectric working fluid under atmospheric pressure was conducted. Boiling curves coefficients different test cases were plotted to evaluate as well captured images samples. Two quantities...

Pool boiling surface modification by pin fin array has demonstrated a practical but effective cooling enhancement. Whilst the main challenge is to determine best configuration of dimensions and positioning, it known that result varies among working conditions. To obtain more general formulation, utterly vital deep understanding pool mechanism during phase-change process. This study aimed analyz...
