A Numerical Study on Turbulent Single-Phase Flow and Heat Transfer in Pillow Plates

Numerical investigation of turbulent forced convection heat transfer in pillow plates

“…In [3] we used a block structured grid for the simulations. The boundary layers were resolved using prismatic cells, which aligned tangentially with the wavy surface.…”

“…Few published works dealing with single-phase flow in pillow plates are by Mitrovic and Peterson [1], Mitrovic and Maletic [2], Piper et al [3] and Tran et al [4,5]. Studies [1,4,5] are of an experimental and [2,3] of a numerical nature. The latter papers focused on gaining a deeper understanding of fluid dynamics and heat transfer in pillow-plate channels.…”

“…In [3], turbulent single-phase flow and heat transfer in pillow plates were studied over the range 1000 6 Re 6 8000 using CFD. The complex pillow-plate geometry was accurately reconstructed using forming simulations, which imitated the manufacturing process of pillow plates.…”

“…The simulation results for pressure loss were validated against measurements of our group and showed a mean deviation of less than 5%. A validation of heat transfer coefficients gained by the CFD model used in [3] was still necessary. Furthermore, the influence of different pillow-plate geometries on the thermo-hydraulic performance was not investigated in [3].…”

“…The results gained in [3] were extended to a large variety of different pillow-plate geometries, thus gaining a more general understanding of the flow and heat transfer characteristics in pillow plates. Furthermore, the influence of the pillow-plate geometry on the thermo-hydraulic performance was investigated revealing the most favorable geometries.…”
