The numerical and analytical methods of calculations of two-dimensional temperature fields in dangerous members of building enclosures

Abstract

The object of research: two-dimensional temperature fields in members of building enclosures, most dangerous from the point of view of a capability of a freezing or vapor condensing in the cold season of year, including in an outside corner and on joints of internal and outside walls and overlaps. The goal of research: the engineering formulas for definition of temperature in stagnation points and cross-sections of the reviewed members and the recommendations for using of these formulas at an estimation of conformity of enclosures to the requirements of thermal safety. The methods applied: the modern numerical and analytical methods of calculations of two-dimensional temperature fields with the experimental endorsement of offered relations for an outside corner of a building by results of full-scale measurements of temperature. The investigation findings: the new regularities of temperature behavior in dangerous members of modern building enclosures and the new values of corresponding numerical coefficients.
