An analysis of the "tree-like network" construct method is presented. The high effective-conduction channel distribution has been optimized, without the premise that the new-order assembly construct must be assembled by the optimized last-order construct. The "tree-like network" construct method...

The relation between heating load and coefficient of performance (COP) of an endoreversible Carnot heat-pump is derived based on a new generalized convective heat-transfer law and generalized radiative heat-transfer law, q [is proportional to] ([Delta]Tn)m. Our results include those...

A diabatic distillation model is improved and the effects of the allocation of a heat-exchanger inventory on the diabatic-distillation performance are taken into account. Minimizing the entropy-production rate of the diabatic distillation column is taken as the optimization objective and the...

The optimal ecological performance of a Newton's law generalized irreversible Carnot engine with losses due to heat-resistance, heat leak and internal irreversibility is derived by taking an ecological optimization criterion as the objective. This consists of maximizing a function representing...

The finite-time thermodynamic performance has been studied of an endoreversible air heat-pump with constant-temperature heat-reservoirs. The heating load, the coefficient of performance (COP), and the heating-load density, i.e. the ratio of heating load to the maximum specific volume in the...

The difficulties, due to a lack of information about stage-by-stage axial-compressor performance, are analyzed. To overcome these issues, a three-layer back-propagation neural-network applied Levenberg-Marquardt algorithm is presented and discussed. The experimental data provided by...

The optimal performance for a class of generalized irreversible universal steady-flow heat-engine cycle models, consisting of two heating branches, two cooling branches and two adiabatic branches, and with losses due to heat-resistance, heat leaks and internal irreversibility was analyzed using...

The constructal economic optimization for a given area is carried out in this paper with minimum transport cost objective by using a triangular elemental area. A number of triangular elements are assembled to form a new larger rectangular area and optimized by relaxing the angle constraint. The...

A model of the behaviour of a two-stage semiconductor thermoelectric heat-pump with external heat transfer is devised. Performance of the heat-pump, assuming Newton's heat-transfer law, is analyzed using the combination of finite-time thermodynamics and non-equilibrium thermodynamics. The...
