Experimental and numerical studies

Experimental and numerical study of the pressure drop and heat transfer in a single-phase micro-channel heat sink by Qu and Mudawar (2002a,b) demonstrated that the conventional Navier-Stokes and energy equations can adequately predict the fluid flow and heat transfer characteristics.

In Chapter 6.1, A. Gutkowski and J. Jarosinski present results of an experimental and numerical study of flame propagation in narrow channels and the mechanism of quenching due to heat losses. This work takes up again classical studies of the quenching distance. The most characteristic features of limit flames are determined experimentally. 

Park and Li [267] also performed an experimental and numerical study in which a serpentine FF with and without diffusion layers was analyzed (see Figure 4.30). For the case in which a DL was not used, an impermeable plate was placed between the anode and cathode plates in order to perform the pressure drop tests. It was observed that the pressure difference between the two cases was as large as 80% of the pressure drop in the case without the DL. It was also explained that the reason for the large pressure difference between both cases was due to the cross-flow phenomena between adjacent channels through the porous diffusion layer. These researchers also performed the pressure drop tests when the fuel cell was running it was observed that the pressure drops were higher in this case than when the cell was inactive. It was believed that this pressure difference was a result of liquid water blocking reactant flow in either the channels or the DLs.

As we will see in the appropriate sections of the next two chapters, the precise ranges of the validity of the Weibull or Gumbel distributions for the breakdown strength of disordered solids are not well established yet. However, analysis of the results of detailed experimental and numerical studies of breakdown in disordered solids suggests that the fluctuations of the extreme statistics dominate for the entire range of disorder, even very close to the percolation point.
