Spacesuit Liquid Cooling Garment Simulator (2D)

This 2D schematic simulator models the same real thermal balance as the 3D Liquid Cooling and Ventilation Garment (LCVG) engine: metabolic heat generated by the astronaut's workload is picked up by chilled water flowing through a network of tubes against the skin, via the real convective heat-transfer relation Q = ṁ·cp·ΔT. Core body temperature is integrated live from the surplus or deficit between metabolic heat and cooling heat removed as you change workload, cooling water flow rate and inlet temperature, with a rolling temperature-versus-time chart and a genuine overheating warning when the computed core temperature crosses the physiological heat-stress threshold.
