Experimental characterization of the thermal performance of the Haines 2 solar cooker
Apaolaza-Pagoaga, Xabier
; Carrillo-Andrés, Antonio; Rodrigues-Ruivo, Celestino (Elsevier, 2022-10-15)
This work presents the most exhaustive experimental characterization of the thermal performance of the Haines 2 solar cooker available to date. Two Haines 2 solar cookers were tested side-by-side in Malaga, Spain, 36.7°N, ... -
Experimental determination of the standardised power of a solar funnel cooker for low sun elevations
Rodrigues-Ruivo, Celestino; Carrillo-Andrés, Antonio; Apaolaza-Pagoaga, Xabier (Elsevier, 2021-02-04)
Over the past few decades, many efficient solar cooker designs have evolved. It is important to measure their performance and communicate this information to researchers, manufacturers and users around the world. Funnel ... -
Experimental method to study the evolution of the performance of solar cookers as a function of solar altitude
Apaolaza-Pagoaga, Xabier; Carrillo-Andrés, Antonio; Rodrigues-Ruivo, Celestino; Jiménez-Navarro, Juan Pablo (2023)
The performance of solar cookers, mainly box cookers and panel cookers, depends on the solar altitude. To study the effect of solar altitude, using the ASAE S580.1 standard or another method that uses liquids. Many tests ... -
Experimental thermal performance evaluation of different configurations of Copenhagen solar cooker
Apaolaza-Pagoaga, Xabier; Carrillo-Andrés, Antonio; Rodrigues-Ruivo, Celestino (Elsevier, 2021-12-01)
In this work, four different configurations of Copenhagen solar cookers were tested experimentally at the same time under the same weather conditions. First tests were carried out using pots without water load. Secondly, ... -
New approach for analysing the effect of minor and major solar cooker design changes: Influence of height trivet on the power of a funnel cooker
Apaolaza-Pagoaga, Xabier; Carrillo-Andrés, Antonio; Rodrigues-Ruivo, Celestino (Elsevier, 2021-08-14)
In present work, the power values of two funnel cookers were determined by following the standard ASAE S580.1 procedure and also a novel improved approach for better analysing the effect of minor design changes. This new ... -
Optical characterization of a funnel solar cooker with azimuthal sun tracking through ray-tracing simulation
Carrillo-Andrés, Antonio; Apaolaza-Pagoaga, Xabier; Rodrigues-Ruivo, Celestino; Rodríguez-García, Eduardo Amador; Fernández-Hernández, Francisco Ángel (Elsevier, 2022-01-20)
Funnel type solar cookers are simple and effective. Most of them rely on a multifaceted reflector to concentrate solar radiation on a cooking pot that is placed inside a transparent enclosure to create a greenhouse effect. ... -
Optical ray-tracing analysis of geometrical variations of a funnel solar cooker.
Carrillo-Andrés, Antonio; Apaolaza-Pagoaga, Xabier; Jiménez-Navarro, Juan Pablo; Rodrigues-Ruivo, Celestino (2023)
Funnel solar cookers are simple, effective and have multiple advantages in practical use. The typology is wide but a large part of the existing designs are based on a 3D funnel-shaped concentrator assembled from a series ... -
Performance of solar funnel cookers using intermediate temperature test load under low sun elevation
Apaolaza-Pagoaga, Xabier; Sagade, Atul; Rodrigues-Ruivo, Celestino; Carrillo-Andrés, Antonio (Elsevier, 2021-08-11)
Solar funnel cookers can be designed as attractive and affordable low-cost devices accessible to people in all continents of the world regardless of their walk-in life. The present work is aimed to investigate the ...
