【摘要】 喷墨过程的数值建模是建立在一维热传导公式,温度—压强关系式和能量、物质转换关系的平衡的基础上的。一维热传导公式用来考虑气泡和它周围液体之间的能量交换以及气—液交界层的温度分布。温度—压强关系式和能量转换关系用来考虑气泡的增长和破裂过程。气泡产生的初始温度、初始压强以及控制电压等参数都在本模型中进行分析,分析的结果为设计喷墨打印机提供了最基础的资料。更多还原

【Abstract】 This model is based on a one-dimensional heat conduction equation,an equilibrium press-temperature relation,energy and mass conservation relations.The heat conduction equation is used to consider the energy transfer between the bubble and the surrounding liquid,as well as the temperature distribution in the liquid layer.The pressure-temperature relation is used to consider the growth and the collapse of the bubble.The bubble generation temperature,initial pressure and the operation parameters are discussed in this model.The result provides a basic guide to the design of bubble jet printers.更多还原
