• Experimental investigations on the boiling process in desorbers are reviewed. Compact membrane and plate based represent trend desorber design. The main contributors to diffusion, convective nucleate boiling. Correlations reported from Absorption technology becomes an attractive option for cooling or heating when driven by solar thermal energy, residual heat different processes, geothermal en...

We present the modeling of the absorption column performance using feed-forward and radial basis function type neural networks. The input and output data for training of the neural networks are obtained from a rigorous model of the absorption column. The results obtained form the neural network models are compared with the results obtained mainly from the simulation calculations. The results sh...

in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

This research deals with heat and mass transfer in biscuit industrial baking ovens. In these ovens, heat reaches biscuits indirectly by radiation, convection and conduction. The method for numerical solution is that we first provide the related equations, then they are discretized by finite difference method (FDM), and finally, after encoding and writing a program for the computer, we run it. T...

The thermo-chemical accumulator (TCA) is a closed absorption batch process that uses a working pair, not only in the liquid, vapor and solution phases but also with solid sorbent, so called triple state operation. It was patented in 2000 (Olsson et al., 2000). Since then the TCA process has been developed in a relatively short space of time by the Swedish company ClimateWell via five generation...

Let q ≥ 1 + 2 N . We prove that any positive solution of (E) ∂tu − ∆u + u = 0 in R × (0,∞) admits an initial trace which is a nonnegative Borel measure, outer regular with respect to the fine topology associated to the Bessel capacity C 2 q ,q in R N (q = q/q − 1)) and absolutely continuous with respect to this capacity. If ν is a nonnegative Borel measure in R with the above properties we cons...
