Steady state thermal
WebMethods of measuring soil thermal conductivity using transient heat flows are considered to be more accurate than steady state methods. Transient methods minimize effects of … WebJan 15, 2024 · 1. Heat flow is governed by the heat equation. ∂ u ∂ t = D ∂ 2 u ∂ x 2. where u ( x, t) is the temperature at a point and D is a constant. The term ∂ 2 u ∂ x 2 describes the curvature of u at a point. The reason that the heat equation goes to a steady state is that moving in the direction of curvature makes the curvature smaller.
