Optimization of Radiative Heat Transfer inside Greenhouses

This paper presents a multi-objective procedure based on a fully elitist genetic algorithm, GA, able to optimize the radiative heat transfer inside greenhouses used to grow crops. Details of the genetic algorithm used is presented herein but the focus is on the heat transfer. The decision variables are the tube temperature and tube radius, that affects directly the entalphy heating flow, and th...

Heat Transfer Analysis of Heating Plate with Multiple Heat Sources

Preliminary note 3D numerical study of transient heat transfer phenomenon on a solid plate with complex heat sources has been carried out. In order to validate the chosen numerical model, a set of thermographic measurements have been performed on a heating plate sample. The infrared camera provided a number of thermograms showing the development of transient temperature fields on the plate surf...

Joule heating and heat transfer in poly(dimethylsiloxane) microfluidic systems.

Joule heating is a significant problem in electrokinetically driven microfluidic chips, particularly polymeric systems where low thermal conductivities amplify the difficulty in rejecting this internally generated heat. In this work, a combined experimental (using a microscale thermometry technique) and numerical (using a 3D "whole-chip" finite element model) approach is used to examine Joule h...

Improving Heat Transfer Efficiency in Heating Ventilation and Air Conditioning Systems Using a Robust Fuzzy PID Controller

High levels of measurement noise, nonlinear and non minimum phase, and conflicting performance requirements pose challenging problems for improving heat transfer efficiency and flow control in HVAC systems. This paper extends the theoretical development of the Energy Delivery Efficiency (EDE) concept to include supply air latent effects and economizer operation, defines how ideal HVAC systems s...

Numerical Study of Heat Transfer and Aerosol Deposition in a Room Environment with Under-floor or Baseboard Heating Systems

In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...
