Liquid Crystals as Phase Change Materials for Thermal Stabilization

Liquid Crystals as Phase Change Materials for Thermal Stabilization

Thermal stabilization exploiting phase change materials (PCMs) is studied theoretically and numerically. Using the heat source approach in numerical simulations, we focus on phase change temperature as a key factor in improving thermal stabilization. Our focus is to analyze possible mechanisms to tu...
