The solution of the two-dimensional inverse heat transfer problem with the use of the FEM in combination with Trefftz functions

Investigation into flow boiling heat transfer in a minichannel with enhanced heating surface

“…Flow structure observation is carried out simultaneously at the opposite side of the minichannel. The "boiling front" is identified as a sudden drop in the temperature of the heating surface following its rise, at constant EPJ Web of Conferences capacity of the internal heat source [1][2][3][4][5][6][7]. It moves upstream together with an increase in the heat flux.…”

“…2c presents the 3D topography of this structure. More data on the enhanced structure can be found in [5] this collection of conference papers. It is possible to observe both surfaces of the minichannel through two openings covered with glass plates (see Fig.…”

“…The local heat transfer coefficient is determined with the use of the two-dimensional model of heat transfer through foil and glass [5]. Similarly to heating surface temperature measurement errors discussed in [1], the mean temperature measured using liquid crystal thermography error is estimated to be 0.9 K. A detailed discussion of heat flux and heat transfer coefficient errors can be found in [1].…”
