Abstract

The critical coating radius of spherical particle in thermal radiation environment was presented for a sphere in a radiation and convection environment, with its industrial application including in combustion of powdered coal or pulverized coal covered with ash layer. The experiment showed that the critical coating thickness was achieved by maximum heat transfer, and the determination of coating thickness is important to achieve the desired nanoparticle performance thereby using more heat to raise the temperature of the cancer cell. The study revealed that the critical radius of the coating increases when either convection or radiation decreases, stating that the existence of the critical radius depends on both the convection and radiation parameters. The increased critical coating becomes feasible to use its radius for heat transfer enhancement for high convection or radiation heat transfer environments.
