... for a physics-based understanding of bubble dynamics associated with plate orifices but also provide critical design tools for industrial applications. Several orifice plates made in materials with different surface energy and hence water-interface contact angle were employed for investigating bubble...

... in the range of ΔT superheat = 8, 10 and 12 ° C. A gradient-based visualization technique, coupled with a high speed camera, has been employed to simultaneously map the changes in thermal gradients during the formation of the vapor bubble as well as bubble dynamic parameters. The image sequence obtained has...

... are obtained at different heat fluxes. The effects of pore density and foam thickness on bubble dynamics and pool boiling heat transfer are revealed. The results show that “bubble entrainment” promotes fluid mixing and bubble sliding inside metal foam. Based on force analysis, the sliding bubble is pinned...

.... The performance is normalized with respect to a plain chip. This investigation also focuses on the bubble dynamics on plain and structured microchannel surfaces under various heat fluxes in an effort to understand the underlying heat transfer mechanism. It was determined that surface modifications to silicon...

...Calvin H. Li; Ting Li; Paul Hodgins; G. P. Peterson Spherical glass and copper beads have been used to create bead packed porous structures for an investigation of two-phase heat transfer bubble dynamics under geometric constraints. The results demonstrated a variety of bubble dynamics...
