Phase Change Material Selection for Efficient Gas to Liquid Heat Transfer
For optimal gas-to-liquid heat transfer processes, identifying the appropriate phase change material (PCM) is paramount. The efficacy of a PCM in this application depends on several critical parameters, including its melting point range, latent storage, thermal conductivity, and chemical stability. Moreover, considering the specific operating temperature of the system is crucial for ensuring efficient heat transfer.

By carefully considering these aspects, engineers can identify a PCM that enhances heat transfer efficiency in gas-to-liquid applications.
Solar heating systems offer a sustainable and environmentally friendly approach to heating buildings. To maximize their efficiency, researchers are exploring advanced heat transfer fluids (HTFs) that can optimize the performance of solar thermal collectors. Traditional HTFs, such as water, have limitations in terms of their energy conductivity and viscosity, which can hinder heat transfer. Advanced HTFs, on the other hand, possess superior properties that allow for more efficient utilization of solar energy.
These innovative fluids often involve specialized materials such as nanoparticles or organic compounds that exhibit higher thermal conductivities and lower viscosities compared to conventional HTFs. This leads to reduced heat losses during the transfer process, resulting in increased energy output from the solar heating system. Furthermore, advanced HTFs can operate at elevated temperatures, enabling them to generate more thermal energy for various applications, such as space conditioning and water warming.
