【摘要】：該文針對現(xiàn)有霧滴與植物葉片交互行為的研究局限于水平葉片的問題,提出了一種基于試驗的液滴與不同傾角的植物葉片交互行為的模擬方法,并設計了一種新的液滴彈跳方向計算方法。首先利用微距高速攝像機對液滴在不同傾角的葉片上的靜態(tài)接觸角大小做了精確測量,并擬合了其隨葉片傾角增大的變化規(guī)律,然后以此將彈跳判定公式推廣到0°~50°范圍內任意傾斜的葉片上。在液滴彈跳方向計算上引入了蒙特卡洛法,代替了原有的鏡面反射計算液滴彈跳方向。模擬結果表明該方法能夠較真實的模擬液滴與任意傾斜葉片的彈跳判定、碰撞、駐留以及飛濺現(xiàn)象。該文提出的方法,為研究霧滴與葉片的交互行為提供新的思路,使得模擬過程的計算量相對較小,為植物冠層與大量霧滴交互的沉積量計算和大規(guī)模植物場景與霧場交互的實施繪制提供了技術參考。
[Abstract]:In this paper, a new method of simulating the interaction between the droplets and the different dip angles of the plant leaves is proposed based on the study of the interaction between the current fog droplets and the plant leaves, and a new method for the calculation of the direction of the drop of droplets is designed. The size of the static contact angle on the blade is measured accurately, and the law of the change with the increase of the blade inclination is fitted, and then the jump determination formula is extended to the blade with any inclination in the range of 0 ~50 degrees. The Monte C Lofa is introduced in the calculation of the drop direction of the droplet and replaced by the original mirror reflection calculation of the drop bouncing square. The simulation results show that the method can simulate the bouncing, collision, residency and spatter of the droplets and any inclined blades. The method proposed in this paper provides a new idea for the study of the interaction between the droplets and the blades, which makes the calculation of the simulation process relatively small and is the deposition of the interaction between the plant canopy and a large number of droplets. It provides a technical reference for volume calculation and implementation of large-scale plant scene and fog interaction.
