Thermal behavior of soils is mainly focused on thermal conduction, and the study of natural convection is very limited. Increase of soil temperature causes natural convection due to buoyancy from density change of pore water. The limitations of the analysis using fluid dynamics for natural convectio...

대류란 ? | 일반적으로 대류는 유체의 움직임에 의하여 열이 이동하는 현상을 지칭하며, 유체의 열확산(molecular thermal diffusion)과 유체의 이동에 의한 열전달인 이류(advection)를 함께 포함하게 된다. 하지만, 열확산이 흙입자와 유체에 의하여 동시에 이루어지는 지반에 대한 열해석에서는 열의 이동이 전도(conduction, thermal diffusion), 대류(convection), 복사(radiation)에 의하여 이루어지는 것으로 구분한다. | |
지반구조물의 열해석을 차지한것은 ? | 지반구조물의 열해석은 동토지역과 같은 기후조건이나 기후변화에 의한 지반거동 특성에 대한 연구가 대부분을 차지하였다. 하지만, 최근에 지반 내부에 인위적인 열원을 설치하거나 지반내 열적 불균형을 해소하기 위한 연구가 활발히 진행되면서, 열이 수리-역학과 연계된 현상들에 대한 중요성이 강조되고 있다. |
