Mathematical and Computer Simulation of the Biological Life Support System Module 2/2. Verification of the model and scenarios

Abstract

According to experimental data a dynamic model of biological life support system (BLSS) module was verified. The soil-like substrate (SLS) lies in the basis of this BLSS. The module was designed for requirements of 1/30 of a virtually present human; it involves higher plants, unit for vegetable wastes processing and gas exchange for carbon dioxide and oxygen. Application of the model helped in estimation of variants of system functioning at optimal and non-optimal modes of illumination and according to the number of age groups in the phytoblock. The alternatives of system development at death of a part or the whole wheat phytomass have been demonstrated, the degree of biotic turnover closedness for C and N in different methods of system mass exchange organization has been estimated. BLSS with SLS exceed the system with physico-chemical method of matter oxidation by the degree of matter turnover closedness. From this viewpoint, SLS based experimental module can become the prototype of new generation BLSS with more high closedness of internal matter turnover.
