Special Issue Information

Dear Colleagues,

This Special Issue follows on from the first Special Issue entitled “Thermal Mechanisms in Solids and Interfaces“ (https://www.mdpi.com/journal/applmech/special_issues/826NA8H6D4). Heat affects materials and systems. Manufacturing processes often involve various forms of heat treatment, favorably transforming the material to a state of higher potential/energy/strength. Utilization processes are often accompanied by heat generation and can involve heat inflow, adversely transforming (i.e., degrading) the material to a state of lower potential/energy/strength. Heat outflow (i.e., cooling) slows down material degradation. Heat transfers through a solid via conduction, and away from the solid (surface) via convection and radiation. In tribological systems involving relative motion between surfaces—dry or lubricated—significant heat generation is induced by friction. With the continuous development of new materials and manufacturing techniques, and the need to optimize in-use processes, understanding thermal phenomena is crucial.

This Special Issue focuses on the thermal mechanisms in solid materials and system interfaces during formation/manufacturing and operation/utilization. The scope of the Special Issue includes the following topics:

  • Microscopic and macroscopic characterizations of thermal phenomena.
  • Modeling and experimental measurements of heat generation, heat transfer, and heat storage, and their impacts on material and system behavior.
  • Frictional heat generation and viscous dissipation.
  • Plasticity-induced heat generation.
  • Cooling and thermal optimization of active mechanical systems.
  • Heat treatment of solids.
  • Temporal and spatial temperature distribution in solids and interfaces.
  • Metals, polymers, and other solid materials.
  • Bearings.

This study proposes a combined finger seal configuration composed of different structural laminates. An equivalent dynamic model of the finger seal system, accounting for thermal effects, is established. The effects of configuration type and operating conditions, including pressure differential, rotor displacement excitation, and temperature, on the dynamic leakage and rubbing force of the combined finger seal are investigated. The finger seal composed of two structural forms (X-type and Y-type) of finger laminates in this paper has a comprehensive advantage in leakage rate and rubbing force compared with the finger seal composed of a single structural seal slice. Compared with the leakage performance of the combined type of finger seals with different finger beam lengths, the maximum leakage rate of the 3Y+2X type finger seal proposed in this paper can be reduced by 29%. For the 3Y+2X finger seal structure and the calculation conditions (including pressure difference, displacement excitation and temperature) of this work, as the pressure difference increases, the seal leakage rate increases, and the peak value and impulse of the rubbing force also increase. The increase in rotor displacement excitation leads to an increase in both the leakage rate and the rubbing force. The increase in environmental temperature leads to an increase in leakage rate of the finger seal, but both the peak value of the rubbing force and the impact force reduce. Under different pressure differences and displacement excitation, the sealing leakage in a 300 °C high-temperature environment is slightly greater than that at normal temperature, but the friction force is less than that at normal temperature.
