Structural and Thermal Analysis of Asphalt Solar Collector Using Finite Element Method

Abstract EN

The collection of solar energy using asphalt pavements has got a wide importance in the present energy scenario.

Asphalt pavements subjected to solar radiation can reach temperature up to 70°C because of their excellent heat absorbing property.

Many working parameters, such as pipe diameter, pipe spacing, pipe depth, pipe arrangement, and flow rate, influence the performance of asphalt solar collector.

Existing literature on thermal energy extraction from asphalt pavements is based on the small scale laboratory samples and numerical simulations.

In order to design an efficient asphalt solar collector there should be a payoff between the thermal and structural stability of the pavement, so that maximum heat can be absorbed without structural damage due to external load condition.

This paperpresents a combined thermal and structural analysis of asphaltsolar collector using finite element method.

Analysis is carriedout in different models so as to obtain optimum pipespacing, pipe diameter, depth, and pipe arrangement under thespecified condition.
