To study the temperature effects which cause degradation of building materials in exterior is necessary to know the coefficient of heat transfer on its surface during the cross-flow. In this paper the values of heat transfer coefficient on circular cylinder for the cross-flow of air characterized by Reynolds number 78 200 were determined. The values of heat transfer coefficient were obtained by comparing numerically computed temperatures in several points in cylinder with measured values of temperatures during experiment.
