Abstract
Climate change has been shaping the world weather patterns also influencing the economic status quo to shift to a more conscious human society. Renewable energy applications have become a trend around the world and the search for a more efficient and feasible technology to harvest energy has increased. The concentrated solar power application has been pointed out by renowned laboratories as a great alternative to fossil fuel power generation, due to that, a heliothermic plant based on the solar tower with free-falling particle receiver has been under development in Sandia National Laboratories. The potential efficiency and feasibility have been showing very promising as the research evolves. As the research in this area increases, it is important to have powerful and trustful tools to develop the knowledge that englobes it. One of the most relevant steps of this kind of research is modeling the phenomena. Therefore, this paper aims to compare the classical modeling particle mass flow equations (Beverloo and British Code) with state-of-the-art equation (Beverloo-Ho) to provide feedback about how they behave in relation of one another. The results confirmed the literature stands that classical equations do not fit very well to predict the particle mass flow in small apertures.
