The typology is wide but a large part of the existing designs are based on a 3D funnel-shaped concentrator assembled from a series of flat reflective panels. The optical performance of a funnel cooker design of this category has already been studied in a previous work. However, there are some interesting geometric aspects that have never been investigated before. The typical funnel geometry has two degrees of freedom to define its shape. This generates a family of variations from the base geometry. The influence of these variations on the cooker optical performance is unknown. This work uses the open source Soltrace ray-tracing tool to improve the understandig of these aspects. This knowledge may be of interest to designers and also to practical users of the funnel solar cooker. eng open access Cocinas (Aparato) Energía solar Ingeniería sostenible Optica geométrica Optical ray-tracing analysis of geometrical variations of a funnel solar cooker. conference output
