One-dimensional heat transfer model for parallel-plate thermoacoustic heat exchangers

In thermoacoustic systems, heat input and output via heat exchangers are important. In this JASA article, the authors derive a 1D model for laminar oscillatory heat transfer between parallel plates, which can be applied in codes such as DeltaEC.

1D heat transfer model for oscillating flow

The authors derive a 1D model for laminar, oscillating heat transfer in parallel-plate thermoacoustic heat exchangers. The model calculates the heat transfer between the solid wall and the acoustic medium, which is essential for heat input and output in thermoacoustic systems. The formulation can be directly implemented in existing (quasi-)1D software such as DeltaEC. The results show good agreement with literature data and demonstrate that acoustic wave phasing does not significantly affect heat transfer in the heat exchanger.

ACME v0.8 has been released!

ASCEE releases version 0.8 of the ACME acoustic measurement platform. This update speeds up analyses for the µZ system by up to three times by saving the Cross Power Spectrum in real time during the test. New features such as automatic signal processing and direct calibration to the DAQ streamline the daily workflow in the laboratory.

µZ System Update and Expansion of Capabilities

ASCEE is launching the new µZ-20 impedance tube for characterizing small meshes and vents for hearables. Without switching microphones, the system measures a wide range from 20 Hz to 8 kHz in a single measurement. This allows engineers to determine the series impedance of small components up to 4,000 MKS Rayls.

Validate your acoustic design choices with hard data

Without measurement data, acoustic product development remains a matter of guesswork. By calibrating numerical models with laboratory measurements, we make vibrations and noise predictable. This helps you avoid errors before the production phase. Discuss your design with us.
