Abstract
To verify model adaptation and flexibility, non-isothermal simulation for perlite expansion has been carried out. Temperature-dependent perlite properties are applied to energy equations for bubble temperature change and perlite melt temperature gradient. Bubble temperature is changed with volume change, water evaporation, and heat flux from melt. Temperature gradient of perlite melt is affected by decreasing bubble temperature. As a result, prediction model and code have been developed below 1100 K with 5% accuracy. At 1100~1400 K, lower 7% accuracy has been obtained from the calculation results.
