Los resultados obtenidos al incluir variaciones el espesor de la placa absorbedora y al añadir dispositivos reflectores que aumentan la capacidad de absorber calor por el sistema, ayudando a que el fluido aumente su temperatura al mejorar el rendimiento general del sistema, las simulaciones computacionales son de gran ayuda para simular entornos operativos hipotéticos que permiten ahorrarse costos por construcción The article seeks to explain how the use of the finite volume method in the discretization of differential equations involved in the modeling of thermal systems is applied in computational simulation programs (CFD). These technological packages have the capability to model complex geometries and heat transfer phenomena, evaluating the interactions between materials to improve thermal efficiency. The results obtained by varying the thickness of the absorber plate and adding reflective devices increase the system's heat absorption capacity, helping the fluid to raise its temperature and enhancing the overall system performance. Computational simulations are highly useful for simulating hypothetical operational environments, allowing cost savings by avoiding construction

The Miraflores Market in San Juan de Lurigancho is an important commercial center for residents of this district, one of the most populated in Lima. Founded in the 20th century, the market has played a crucial role in the local economy, facilitating the trade of fresh food and other essential products (Garcia, 2015). The district of San Juan de Miraflores has a population of 430,772 inhabitants, of which 216,900 are men and 213,872 are women. The infant mortality rate in the district is 9.2% per thousand inhabitants. In the specific case of Peru, the lack of effectiveapplication of meat handling in these companies with such activity raises serious concerns in terms of Public Health and Food Safety. It is important to highlight that the sanitary hygiene conditions and the handling of meat products were investigated with the aim of relating them to food-borne illnesses. On the other hand, alternatives for improvements in the handling of meat products for retailers were established.

Los resultados obtenidos al incluir variaciones el espesor de la placa absorbedora y al añadir dispositivos reflectores que aumentan la capacidad de absorber calor por el sistema, ayudando a que el fluido aumente su temperatura al mejorar el rendimiento general del sistema, las simulaciones computacionales son de gran ayuda para simular entornos operativos hipotéticos que permiten ahorrarse costos por construcción The article seeks to explain how the use of the finite volume method in the discretization of differential equations involved in the modeling of thermal systems is applied in computational simulation programs (CFD). These technological packages have the capability to model complex geometries and heat transfer phenomena, evaluating the interactions between materials to improve thermal efficiency. The results obtained by varying the thickness of the absorber plate and adding reflective devices increase the system's heat absorption capacity, helping the fluid to raise its temperature and enhancing the overall system performance. Computational simulations are highly useful for simulating hypothetical operational environments, allowing cost savings by avoiding construction

The Miraflores Market in San Juan de Lurigancho is an important commercial center for residents of this district, one of the most populated in Lima. Founded in the 20th century, the market has played a crucial role in the local economy, facilitating the trade of fresh food and other essential products (Garcia, 2015). The district of San Juan de Miraflores has a population of 430,772 inhabitants, of which 216,900 are men and 213,872 are women. The infant mortality rate in the district is 9.2% per thousand inhabitants. In the specific case of Peru, the lack of effectiveapplication of meat handling in these companies with such activity raises serious concerns in terms of Public Health and Food Safety. It is important to highlight that the sanitary hygiene conditions and the handling of meat products were investigated with the aim of relating them to food-borne illnesses. On the other hand, alternatives for improvements in the handling of meat products for retailers were established.
