In this study, a comprehensive heat transfer investigation of steel plate using zinc/aluminum layered double hydroxide (Zn/Al-LDH) nanofluid in jet cooling application is reported. Continuously, a robust correlation between the thermal conductivity and heat transfer was established with respect to the Zn/Al-LDH nanofluid concentration. In details, the highest cooling rate was observed to be 129 oC/s at 150 ppm nanofluid concentration. Surface heat flux maximum value of 2.4 MW/m2 was acquired. Simultaneously, the resultant Zn/Al-LDH nanoparticles were characterized using powder X-ray Diffraction technique (PXRD), Fourier Transform-Infrared Spectroscopy (FT-IR), and Field Emission Scanning Electron Microscopy (FESEM). Particularly, the particle features using FESEM technique was found to be of a plate-like shape and diameter of 43 nm. In conjunction with the aforementioned, it was found that the present study represents a cost-effective and eco-friendly nanofluid for high surface flux applications.
