Abstract

The intermittent requirement of the energy systems like process heating, district heating, and power generation provides the motivation to develop a stable thermal energy storage system. This work presents the experimental results obtained from a sensible thermal energy storage system configured with concrete perforated cylindrical blocks. The perforated cylinders inside the bed are arranged in the staggered arrangement. The geometrical parameters of perforated cylinder blocks are the number of perforations (Nh) ranges from 2 to 6 and the perforation ratio (Dr) ranges from 0.2 to 0.6, respectively. The flow Reynolds number (Re) in the present study ranges from 1200 to 3200. The research results reported the maximum Nusselt number (Nu) and friction factor (f) obtained at Dr = 0.6 and Nh = 6, respectively. The maximum thermo-hydraulic performance (η) of 0.19 is obtained for Dr = 0.6, and Nh = 6 at Re = 1200, respectively. The perforated cylindrical elements are found suitable for the thermal and momentum transport improvement of the thermal storage packed bed system.
