Human body thermal simulation modeling method suitable for complex space environment

Abstract

The invention relates to a human body thermal simulation modeling method suitable for a complex space environment. The method is characterized in that the method comprises: dividing a human body model into a human body hyperpyrexia core area (11), a blood perfusion area (12) and an equivalent tissue heat transfer area (13) from inside to outside; and solving the temperature distribution of the human body hyperpyrexia core area (11), the blood perfusion area (12) and the equivalent tissue heat transfer area (13) by adopting an unsteady state heat transfer equation. In the invention, by introducing the self-thermoregulation behavior of the human body, the temperature distribution of a human body surface is obtained, and the narrow limitation in the prior art that the thermal comfort of the human body is judged only by environmental parameters is changed. In the invention, on the basis of the fluid-solid conjugate heat transfer analysis theory, the temperature field of the solid area of a human tissue is obtained, and the numerical value simulation of heat transfer process inside a human body model in a large space is realized.

Description

technical field [0001] The invention relates to a human body thermal model with thermal adjustment capability, which is suitable for human body heat transfer analysis and human body thermal comfort design in a large complex space environment. Background technique [0002] Thermal comfort is an engineering concept proposed in the early 20th century, and it is an indicator used to reflect the subjective psychological perception process of the human body to the surrounding environment. In the past, the thermal comfort research for large and complex spaces mainly used numerical calculation methods. By establishing the relationship between the thermal comfort evaluation index and the surrounding thermal environment, we explored the changes in environmental parameters and the thermal comfort of the human body, so as to achieve the evaluation and prediction of comfort with environmental parameters. sex. Due to the constraints of the adaptability of human body surface modeling in C...

Problems solved by technology

[0008] - Although the box-shaped human body modeling maintains the shape of the human body to a certain extent, it cannot completely and accurately reflect the influence of the complex geometric shape of the human body on the spatial air flow field

[0009] - Although the existing curved surface dummy human body modeling keeps the shape of the human body as much as possible and reflects a more reasonable human body heat transfer effect as much as possible, such as Figure 2c , but this also brings about a huge amount of calculation. If it is applied to the heat transfer and comfort analysis of multiple people in a large and complex space environment, it will lead to a calculation disaster for the heat transfer and comfort analysis of multiple people in a complex space.
