  • Novel cost effective configurations of combined power plants for smalls scale cogeneration from biomass design of the particle heat exchanger

    A general design procedure have been developed for the application of the Immersed Particle Heat Exchanger to a novel, small scale, externally fired combined cycle capable of generating electrical and thermal power from carbon-neutral biomass. The Immersed Particle Heat Exchanger serves as the high temperature heat exchanger needed to couple the Brayton cycle with an external combustor of biom

  • Novel, cost-effective configurations of combined power plants for small-scale cogeneration from biomass

    The employment of small combined cycles as a valid alternative to ORC systems for Combined Heat and Power from biomass is feasible in the near future and can guarantee competitive thermodynamic performances. Two design optimizations were performed according to two different configurations, employing the Immersed Particle heat exchanger and Nickel Alloy heat exchanger. Thermal efficiency and electrical efficiency were selected as the objectives to be maximized by the optimization algorithm in modeFRONTIER.

  • Parametric analysis of heat exchanger for thermoelectric heat pump

    The purpose of this work is the implementation of a standard and well proven procedure for the optimization of Heat Exchangers' performance for general thermoelectric applications. The interest in investigating such a methodology comes up as a consequence of a new production technology just developed for finned heat exchanger.

  • Development of high efficiency heat exchanger for Air-conditioner using optimization technique

    In this paper, the new technique of the optimization, especially for heat and fluid problems which has a complicated design area of solution that consists of many design variables, is proposed. It is characterized by dividing design area applying data-mining to the sampled dataset, and advancing optimization for every design area. The proposed method is applied to the development of the heat exchanger fin, and the result verifying the validity is reported.

  • Optimal design of the heater of a Stirling engine coupled with a fluidized bed combustor

    The idea of using heat generated by combustion as a source for a Stirling engine dates back to the early achievements of Stirling Engines (SE). The original idea is to place the hot head of the engine as much as possible in direct contact of the flame generated by combustion, identifying the flame with the region of highest temperature and therefore as that which favors thermal exchange between the hot combustion gases and the working fluid of the engine
