Thermical Phase Shift Determination Around Vertical Bridges
MetadataShow full item record
The way this concept is defined (in the prescription) is not the most proper for technical regulations where more clear and precise formulations are required especially when important concepts are defined. The estimation of the corrected thermal resistance is based on the method of linear and punctual thermal transfer factors that are not defined in C107 – Prescriptions. Also the expression (equation) proposed for the estimation of the linear transfer factor y , although practicable, is stated in an inhomogeneous and incomplete manner. For the assessment of these parameters are recommended the expressions that result from the analytical solving of the differential equation of heat lose, in unidirectional unsteady conditions, considering some simplified hypothesis.
