This paper presents a new stepwise approach to design a medium-temperature solar
parabolic trough collector with a secondary reflector, which is the fastest growing technology …

Non-uniform solar flux distribution in a parabolic trough concentrator (PTC) causes large
temperature gradients on absorber tube surface, making the PTC inefficient and damaged …

This chapter describes the basic relations, components, classifications, and applications of
concentrating optical collector systems for solar thermal and thermochemical applications …

Parabolic dish concentrators have demonstrated the highest thermal and optical efficiencies
among the available concentrator options. This paper proposes a novel design approach for …

The aim of the present work is to enhance the thermal management avoiding the high‐

The non–uniform solar flux distribution on the absorber surface in a parabolic trough
collector results in a large temperature gradient and stress, thus leading to safety hazards …

In this article, a V-shaped ribbed tube is utilized to improve the thermal performance of a
parabolic trough collector (PTC). Six different rib arrangements are employed, and a …

The maximum concentration ratio of the commercial parabolic trough collectors is limited to
42% of the theoretical limit of concentration. Recently, the secondary flat reflector geometry …

In the present study, experimental investigation of parabolic trough collector is carried out as
per ASHRAE 93-1986 standard. In this study, two different case of receiver involving …

The performance of the newly designed parabolic trough solar thermal collector system has
been investigated experimentally in the current work. The receiver tube is placed below the …
