Numerical simulation of oscillatory flow and heat transfer in the heat exchangers of therm

A numerical simulation dataset from a study applying the RANS method with SST k-ω turbulence model to solve time-dependent turbulent Navier-Stokes and energy equations. The work, by Olusegun M. Ilori of the University of Leeds, models oscillating helium gas flow and heat transfer in three parallel plate heat exchangers arranged in series. The code was validated against analytical solutions, and the study details the effects of pressure oscillation and three channel edge shapes (blunt, cone, ogive) on flow and heat transfer.

Use Cases

• Validating CFD models for oscillatory flow based on the described RANS method and turbulence model.
• Analyzing the impact of pressure oscillation on velocity and temperature distributions in heat exchangers.
• Comparing the performance of different heat exchanger channel edge shapes (blunt, cone, ogive) on flow behavior.
• Supporting the design of next-generation thermoacoustic systems by studying heat exchanger requirements.

Strengths

• Numerical code was validated by comparing results to analytical solutions found in the literature.
• Study investigates three distinct heat exchanger channel edge shapes, providing comparative data.
• Simulation is based on solving time-dependent turbulent Navier-Stokes and energy equations for a specific physical setup.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
