Abstract

The Virtual Habitat project (V-HAB) at the Technical University of Munich (TUM) aims to develop a dynamic simulation environment for life support systems (LSS). Within V-HAB a dynamic human model interacts with the LSS by relevant metabolic inputs and outputs based on internal, environmental and operational factors. The human model is separated into five sub-models (called layers) representing metabolism, respiration, thermoregulation, water balance and digestion. While previous effort was conducted in order to make the Wissler Thermal Model in its current accepted version available in V-HAB, present work is focusing on the passive system. As a part of this work the entire inner build-up of the human body concerning organ size and tissue distribution was reworked. Data was collected for the main tissues within the human body – Blood, Bones, Active & Inactive Bone Marrow, Brain, Fat, Heart, Kidneys, Liver, Lung, Muscle, Skin, Spleen, and Visceral. As the V-HAB project is intending to use the reworked Wissler Thermal Model for simulation of astronauts, who are of various ethnical backgrounds, can be both male and female and of various age (18 to 60+) it was decided to take all these parameters into account. The current work focusses on the assessment of age-related organ size changes in various populations and the overall assessment performed for the Wissler Thermal Model’s inner tissue distribution assessment.
