The condition obtained involves solar radiation and convective heat transfer, other terms were shown to be small compared to these. It is shown that this boundary condition leads to a temperature variation that has qualitative agreement with experiments carried out by the Cement and Concrete Institute. date: 2004 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/65/1/surfacebc.pdf identifier: Charpin, J.P.D. and Myers, T.G. and Fitt, A.D. and Ballim, Y. and Patini, A.
