INNOVATIVE THERMODYNAMICAL CYCLES BASED ON ENHANCEMENT MASS, MOMENTUM, ENTROPY AND ELECTRICITY TRANSPORT DUE TO SLIP, MOBILITY, TRANSPIRATION, ENTROPY AND ELECTRIC JUMPS AS WELL AS OTHER NANO-FLOWS PHENOMENA
Abstract
In our work, a further development of the authors model of thermo-chemical flow of fuel, air, oxygen, steam water, species, ionic and electron currents within nano channels and nano-structures of novel devices is presented. Different transport enhancement models are taken into account -among them the most important are: the velocity slip connected with complex external friction, the Darcy mobility and the Reynolds transpiration. Increasing gas path to the triple-phase-boundary (TPB) enhances mass and electricity fluxes due to the concentration jump and the electron resistivity jump. Enhancement of heat transport due to the von Smoluchowski jump is considered within the frame of generalized model of Navier-Stokes slip boundary condition. Particular elements of the model have been tested and calibrated on the literature benchmark experiments concerning nano-flows, nano-combustion, nano-condensation and separation. Integrated geometrical characteristics of working fluids and canal materials such as: porosity, tortuosity and mean radii are finally involved into a macroscopic continuum model, and implemented into the standard CFD code. As a result of analysis the production characteristics have been examined and compared with the benchmark data.
