Identification of unifying heat transfer mechanisms along the entire boiling curve

A study of local heat transfer mechanisms along the entire boiling curve by means of microsensors

“…This difference is not important for the purpose of this paper; for a discussion of the effect we refer to [6]. The measured temperature at the MTC location is very close to the real surface temperature with respect to value and dynamics which has been shown by a solution of the inverse heat conduction problem [24]. The horizontal distance between the thermocouple junctions of the neighboring MTCs Nos.…”

“…This approach has been employed to model pool boiling along the entire boiling curve successfully in [24].…”

Reconstruction of local heat fluxes in pool boiling experiments along the entire boiling curve from high resolution transient temperature measurements

“…In our previous work, we solved a similar IHCP to estimate the surface heat flux and the surface temperature fields from temperature readings [13,26]. In contrast to this work, only a two-dimensional (2D) heat conduction model with unknown boundary conditions at the heater surface has been set up before.…”

Non-linear dynamical analyses of transient surface temperature fluctuations during subcooled pool boiling on a horizontal disk

“…Earlier efforts [5] in this field employed spatially and temporally averaged data in developing models to predict the heat fluxes. The importance of measuring surface temperatures with adequate spatial and temporal resolution in pool boiling systems has recently gained emphasis [6,7]. Micro-fabrication techniques can provide the necessary spatio-temporal resolution needed for a thorough understanding of the phase change process.…”

“…Ahn et al [17] used thin film thermocouples to measure the surface temperature fluctuations in film boiling in order to verify the presence of cold spots. Lüttich and others [6,7], recently used micro-machined TFT to estimate the surface temperature and heat flux fluctuations in pool boiling. However, the TFT was covered with a sputtered layer of gold 0.001 mm in thickness leading once again to an indirect estimation of surface temperature and heat fluxes.…”
