Increasing electricity generation-Installing photovoltaic cells coupled to a battery pack, to provide the electricity

摘要

By 2050, renewables should increase the share of electricity generation to 70 . According to the net-zero long-term plan, solar energy is at the forefront of renewable sources. The concreted solar plant is one of the best renewable-based electricity generation utilities that can combine with solar cells and battery systems. In this study, basic modelling for counter flow shell-tube type heat exchanger is developed in which melted salt and steam/water are the two-working fluid of the heat exchanger. A two-phase heat transfer analysis has been considered for the boiling phenomena in the saturated steam region. The study is performed for 5 kg.s(-1) flow rate of steam/water and for different flow rate of melted salt varying from 75 kg.s(-1) to 300 kg.s(-1). Thermodynamic characteristics of the heat exchanger, such as, vapor quality and convective coefficient variation of the steam/water along the length of the heat exchanger has been presented. In addition, temperature profile of the melted salt and the steam/water along the length of the heat exchanger is determined in this study. Numerical analysis affirmed that the battery cooling was successful at Reynolds number of 200-500 as the maximum temperature was lower 320 K.
