| چکیده | ||
| Phase change materials (PCM) can be employed in many fields due to their capacity to absorb and release energy when it is necessary. Nowadays, the number of studies about these kinds’ materials is increasing because of their benefits in the energy storage systems. In microencapsulation, the core material is defined as the specific material coated and can be in the liquid or solid state depending on the temperature. In this research, two new PCM microcapsules based on palmitic acid (PA) core and silicon dioxide (SiO2), strontium titanate (SrTiO3) were shelled and synthesized through self-method in three core/shell weight ratios (50/50, 40/60, 30/70). Finding the thermal properties of these materials experimentally, then the thermal simulation in rectangular energy storage was performed under the constant heat flux. The simulated results were analyzed and discussed. Among the synthesized microcapsules, the best results were PA@SiO2 with a weight ratio of 30/70. This sample had maximum amount of 24.42% melting time in 12,000 seconds and the maximum temperature at 369 K, which indicated 196.8% higher than the pure PA. | ||
