摘要:
设计并采用MEMS工艺制造了一种特征尺寸10 μm并能产生单一稳定微米气泡的Pt薄膜加热器。在不同加热脉冲宽度条件下(100~1 000 ms),用CCD摄像头和MATLAB程序定量研究了在乙醇、除气水和纳米流体中微气泡的动力学过程。研究发现:不同流体中,随着脉冲宽度的增加气泡直径增大,所需的起始功率减小。乙醇中气泡成核所需的功率最小,气泡直径最小;而纳米流体中所需功率最大,气泡直径也最大。通过表面张力与成核的理论模型对此进行了初步的理论分析。
Abstract:
A Pt microheater, with a feature size of 10 μm and capable of generating stable single thermal bubble, was designed and fabricated using micro electro mechanical system technology. Under various heating pulse width, ranging from 100-1 000 ms, the bubble dynamics in ethanol, degassed water and nanofluids was quantitatively investigated with CCD camera and a MATLAB program. We found that for all the working fluid, the initial input power increased with the heating pulse width. In addition, for initial bubble generation, the required input power was minimum in ethanol, while it was maximum in nanofluids. Also, the bubble size was maximum in ethanol and maximum in nanofluids. Preliminary analysis on this phenomenon was carried out by using a surface tension and bubble nucleation theory.
