Modeling and analysis of a dual-acoustic-driver thermoacoustic heat pump
Geng Chen,Lihua Tang,Zhibin Yu +2 more
TL;DR: In this paper , the authors investigated the effects of acoustic drivers on the acoustic and thermal characteristics of a dual-acoustic heat pump (TAHP) and found that the acoustic field in the TA core could be dominated by a standing, traveling, or hybrid standing-traveling wave.
Journal ArticleDOI
Single-objective Optimization for Stack Unit of Standing Wave Thermoacoustic Refrigerator through Particle Swarm Optimization Method
TL;DR: In this paper, the stack unit is considered as the key element responsible for thermo-acoustic cooling effect, and particle swarm optimization (PSO) is introduced as an intelligent method for such optimization.

TL;DR: In this paper, an approximate analysis of energy flow and acoustical measurements of a thermoacoustic prime mover with arbitrary cross-sectional geometry is given. But this analysis is restricted to the case of TAEs with circular or parallel slit pore geometry.

Transition to turbulence in oscillating pipe flow
P. Merkli,H. Thomann +1 more
TL;DR: In this paper, the authors used hot wires and flow visualization by means of smoke, and provided new details on turbulence in a Stokes layer, showing that turbulence occurs in the form of periodic bursts which are followed by relaminarimtion in the same cycle and do not lead to turbulent flow during the whole cycle.

Experiments on the turbulence statistics and the structure of a reciprocating oscillatory flow
TL;DR: In this paper, a reciprocating oscillatory turbulent flow in a rectangular duct is investigated experimentally by making use of a laser-Doppler velocimeter, hot-wire anemometers as well as electronic digital sampling and processing equipments.

An investigation of transition to turbulence in bounded oscillatory Stokes flows Part 1. Experiments
TL;DR: In this paper, the authors used a two-colour laser-Doppler anemometer to measure Axial and radial velocity components of turbulent flow in a circular pipe for the range of Reynolds numbers Reδ = U0δ/ν (U0 = amplitude of cross-sectional mean velocity, δ = (2ν/ω)½) = Stokes layer thickness) from 550 to 2000 and Stokes parameters Λ = R/δ (R = radius of the pipe) from 5 to 10.
