0 ResultsProject: VENTINOVA — Multi-Tube Terracotta Venturi Evaporative Cooling System and Carbon Filter Simulate airflow and heat/mass transfer through a dual-venturi evaporative cooling system housed in a 50L enclosed chassis. Ambient air is drawn in by a 220V, 8-inch axial fan and passed through two parallel 150mm OD unglazed terracotta pipes arranged in a venturi (converging-diverging) configuration. Each terracotta tube is continuously wetted via a gravity-fed drip equalization bar supplied from a 6-liter overhead water tank, allowing porous evaporative cooling as air accelerates through the venturi throat. Downstream of the terracotta tubes, air passes through a carbon filter stage for particulate/odor filtration before exiting through a passive humidity bypass duct, which vents a portion of excess humid air to prevent over-saturation of the outlet stream. CaCl₂·6H₂O phase-change material sachets are positioned along the tube walls to buffer thermal fluctuations and extend the cooling effect during peak ambient temperature swings. Simulate for: Airflow velocity and pressure drop across the venturi throat (accelerated flow zone) Evaporative cooling effect — temperature drop (°C) and relative humidity rise (%) from inlet to outlet Effect of dual-tube parallel configuration vs single-tube on flow distribution and cooling uniformity Pressure loss contribution from the carbon filter stage Thermal buffering effect of PCM sachets on outlet air temperature stability over a 2–4 hour cycle Boundary conditions: ambient inlet at typical Indian summer conditions (~38–42°C, 20–30% RH), fan-driven forced convection, porous media model for terracotta wall evaporation Goal: Validate that the dual-venturi terracotta design achieves a measurable temperature drop (target: 8–12°C) and acceptable pressure drop for the given fan capacity, while confirming the carbon filter and bypass duct don't significantly choke airflow.
