本文对一个适用于沉积盆地形成的潜热随空间变化的熔融模型进行了数值研究。几何形状是矩形通道，其在长度方向上具有线性增加的潜热，并且在宽度方向上具有梯度对比度。熔体前沿由热通量驱动。引入适当的缩放后，它示出的熔体前沿的形状的显着演变发生在5宽度的通量边界和熔体厚度（最先进的部分和最先进的熔体前沿之间的下游长度）的比例与潜热斜率的比率的日志。
A melting model with spatially varying latent heat (applicable to the formation of sedimentary basins) is numerically investigated. The geometry is a rectangular channel with linearly increasing latent heat in the length direction and a step contrast in slope in the width direction. The melt front is driven by a heat flux. After introducing suitable scaling, it is shown that the significant evolution of the shape of the melt front occurs within 5 widths of the flux boundary and that the melt-thickness (the downstream length between the most and least advanced parts of the melt front) scales with the log of the ratio of latent heat slopes.
