要可靠估算潮汐冰川的融化速率，需精准掌握近垂直冰-海界面的盐通量与热通量，而当前相关认知仍存在不足。本文针对无限垂直通道内的湍流双扩散对流这一理想化系统，提出盐通量与热通量理论，并展示该理论可如何扩展，以给出海水中垂直冰面的浮力驱动融化速率的理论估算。我们的理论结果与直接数值模拟数据及实验室实验测量值吻合良好。
英文摘要
Reliable estimates of the melt rate of tidewater glaciers require accurate knowledge of salt and heat fluxes at the near-vertical ice-ocean interface and such knowledge is currently lacking. In this paper, we present a theory for salt and heat fluxes in the idealized system of turbulent double-diffusive convection in an infinite vertical channel and show how this theory can be extended to give theoretical estimate of the buoyancy-driven melt rate of a vertical ice surface in seawater. Our theoretical results are shown to be in good agreement with direct numerical simulation data and measurements from laboratory experiments.
