Overview

Experimental analysis shows enhanced thermal performance in solar air heaters using PCM and flow turbulators.

Key Points

  • The modified double-pass solar air heater integrated with PCM shows improved thermal performance over conventional designs.
  • Outlet air temperature increased by about 22%, 14%, and 9% in modified cases compared to the conventional system.
  • Using V-shaped flow turbulators achieved a thermal efficiency improvement of 35%, outperforming other designs.
  • The use of phase change materials extended operating time by 2 hours after sunset, enhancing overall efficiency.
