| description | Geothermal energy has become one of the indispensable renewable energy in the energy development in the 21st century, and it is also one of the most realistic and competitive energy. The orc power generation test system with low temperature heat source (60 ∼ 90 °C) is designed, and the key component horizontal tube falling film evaporator is designed. The experimental results show that the heat transfer coefficient increases with the increase of evaporation temperature in the range of 40 ∼ 65 °C. The experimental results show that when the spray density is in the range of 0.010 ∼ 0.025 kg/m K, the heat transfer coefficient increases with the increase of spray density. The experimental results show that when the hot water mass flow rate is in the range of 0.06 ∼ 0.18 kg/s, the heat transfer coefficient increases with the increase of hot water mass flow rate. |
