Abstract

The primary goal of this research is to create a new billboard-style central spherical solar receiver with varying header and tube diameter, for which two spiral central receiver designs and a new circular central solar receiver with varying pipe radius and varying mass circulation are utilized. The exhaust temperature of the water was determined employing a computational fluid dynamics assessment employing ANSYS Fluent. Following the verification of the standards models, a novel central solar receiver project was made that accomplishes computational fluid dynamics assessment with almost the same boundary condition.The heat export fluid is water, and the spiral coil tube is copper. The mass circulation rate varies among 0.1 LPM, 0.2 LPM, and 0.3 LPM, with the inlet temperature of water being 299K at continuous solar irradiation. The findings demonstrate that at 0.1 LPM, the redesign of the central solar receiver produces a temperature of 383.9 K, which is 28.39 percent higher than the inlet temperature and 7.32 percent higher than the spiral central receiver. As a consequence, the circular central solar recipient to varying pipe radius is suggested and considered in upcoming usages

Highlights

Solar thermal technologies, in overall, are founded on the idea of concentrating solar radiation to convert water into steam or hot air, that can be used to generate electricity employing traditional thermal - dynamic power cycles

Summary

Introduction

In overall, are founded on the idea of concentrating solar radiation to convert water into steam or hot air, that can be used to generate electricity employing traditional thermal - dynamic power cycles. Reflectors concave geometry, visually affiliated mirrors, and parabolic shaped devices are used to concentrate uniform solar irradiation. Due to various their high reflectivity, most processes employ glass mirrors for concentration. The centralized receiver framework, known as a heliostat, just at top of a tower is used to concentrate on sunlight to a received signal in a sun-tracking mirror system. The transceiver is used to produce steam in a heating medium warmed to about 600 degrees Celsius, which is used to generate electricity in a traditional turbine
