Investigation of Parametric Performance of the Hybrid 3D CPC/TEM System Due to Thermoelectric Irreversibilities

The effects of the device performance parameter, denoted as ψ, due to thermoelectric irreversibilities on the hybrid compound parabolic concentrator and the thermoelectric module (3D CPC/TEM) system for power generation, have been investigated. The dependence of the behavior of the parameter on the thermoelectric irreversibilities is highlighted. The paper shows that when ψ is plotted against the collector thermal efficiency, a linearized plot is obtained. When plotted against the other system's output parameters, the resulting plots exponentially decay. The plots could be used for determining the desirable range for good performance of the system. The linearized plot could be useful in the determination of the values of the receiver plate temperature and the heat loss from the collector

Computational Modeling of Trombe Wall Solar Chick Brooding House for Optimal Poultry Production

Computational modeling, simulation and validation were carried out on Trombe wall solar chick brooder used for optimal poultry production. Predictive linear differential equations based on physical, mathematical principles and relationships governing thermo-physical properties of the components of the brooder were formulated, discretized and expressed in their finite different forms using SCILAB 5.5.2. T-test statistics was carried out on predicted and measured mean data: temperature of Trombe wall glaze (TG1), temperature of pebble glaze (TG2), temperature of the pebble bed bin (Tp), temperature of the brooding room (TBr), and temperature of the Trombe wall outer surface (Tw (outer surface))then separated using Levene test for equality. The model adequately predicted the measured temperature of the brooding brooder at 5% probability level
