In engine combustion systems such as rockets, aero-engines and gas turbines, pressure
fluctuations are always present, even during normal operation. One of design prerequisites …

How to improve the efficiency of heat transport, conversion and management has been the
research focus of thermal energy application and related disciplines. Since the Field …

In this work, we develop a 2D numerical model of a Y-shaped bifurcating combustor with a
Helmholtz resonator attached. Propane (C 3 H 8) is fueled and burnt with air by applying …

Combustion instabilities in a Rijke tube could be triggered by the transient growth of flow
disturbances, which is associated with its non-normality. In this work, a Rijke tube with three …

Self-excited combustion instabilities are characterized by large-amplitude limit cycle
oscillations of thermodynamic properties such as pressure, velocity and heat release. In …

A metamaterial-inspired triboelectric nanogenerator (META-TENG) is proposed in this work
to simultaneously realize vibration suppression and energy harvesting. The compact META …

This paper presents a systematic investigation of the performance of particle dampers
(vertical and horizontal) attached to a primary system (single-degree-of-freedom (SDOF) and …

Noise reduction for aircraft engine has attracted great concern due to the strict noise control
regulation nowadays. Conventional perforated sheet-over-honeycomb acoustic liners have …

In this work, a convection-driven Rijke–Zhao thermo-acoustic-piezo system is designed and
experimentally tested to demonstrate its potential for harvesting thermal energy. For this, a …

Periodic acoustic structures of rigid micro-rods produced via additive manufacturing were
analyzed using an impedance tube in the 500 Hz–6000 Hz frequency range. The acoustical …
