Thermal investigation of a solar box-type cooker with nanocomposite phase change materials using flexible thermography

In this study, three SBCs are developed as (i) SBC with phase change material (PCM: waste cooking oil and C 4 H O 3 ), (ii) a novel nanocomposite PCM (NPCM), (iii) without NPCM. The proposed cooker integrated NPCM (MgAl 2 /Ni/Fe -PCM) was experimentally its performance evaluated using fuzzy logic Cramer's rules, image processing techniques. results indicated that the implementation of bar plate absorber coated MgAl /Ni-doped, Fe nanoparticles, increases cooker's internal temperature up to 164.12 °C. used materials were in average particle size 20 ?m. verified segmentation process. SBC's thermal enhancement 11% comparison Additionally, overall NPCM, PCM, obtained 24.90–33.90%, 24.77–45.20%, 31.77–56.21%, respectively. Moreover, achieved 163.74 °C, 147 113.34 °C for respectively, under solar radiation 1,037 W/m .
