Abstract. In the article research results are presented, which aim to provide of automation
algorithm mathematical model of designing technology clothing of the cold protection. The
method of calculating heat transfer in the "human - environment" system takes into
account the variable thermal parameters and the geometric dimensions of the elements, the
presence of internal heat sources and
... [Show full abstract] convective heat transfer with the heat-carrier flow along
the layers and between the calculated elements . Then the problem is reduced to a onedimensional
heat conduction problem with a variable thermal conductivity coefficient. When
modeling a human body, we assume that each element of the model is represented as a set of
elliptical cylinders forming the inner layers. Four main concepts of the geometric
representation of the outer and inner solutions of the human body model have been developed
to simulate the problems of human heat exchange with the environment. An algorithm is
proposed for determining the type and structure of a mathematical model for use in CAD
systems of protective clothing designing. The research was made in Don State Technical
University within the framework of State Assignment of the Ministry of education and science
of Russia under the project 11.9194.2017/BCh.
