【摘要】 数值模拟了流体在不同圆锥角度和不同入口尺寸的新型涡旋发生器中的压力分布和传热特性。结果表明,新型涡旋发生器可以有效降低吸收式制冷系统发生器内的蒸发压力和流体的发生温度,从而可以充分利用太阳能等低品位热源、提高系统的性能系数。更多还原

【Abstract】 Numerically simulates the pressure distribution and heat transfer characteristics of fluid in a new vortex generator with different conic angles and different inlet sizes. The results indicate that the generator is beneficial to reducing the pressure in the generator and the saturate temperature of fluid, thus the solar energy and other low quality energies can be sufficiently used and the coefficient of performance of the absorption chiller system improved.更多还原
