Toward an Understanding of the Indirect Climatic Effect of Aerosols [PDF]
, 2003 This thesis is motivated by the need to improve our understanding of the aerosol indirect effect. The activation of aerosol into cloud droplets has been extensively studied, using a comprehensive numerical cloud droplet activation model. Using this model,

Complex Behavior of Droplet Transfer and Spreading in Cold Metal Transfer [PDF]
Shock and Vibration, 2020 In intelligent manufacturing, an intelligent control method of welding process is an important process of intelligent welding manufacturing technology (IWMT). Metal transfer is a key factor to control the welding process. Metal transfer and droplet spreading are of vital importance for welding formation.

Heat transfer within combusting droplets [PDF]
Proceedings of the Combustion Institute, 2007 The improvement of the basic understanding of heat transfer in sprays is a key point in many engineering applications. In this paper, the temperature field within combusting ethanol droplets in linear stream is investigated by the two-color laser induced fluorescence technique. Additionally, a heat transfer model within the droplet is developed, taking

Droplet Transfer in Two Phase Annular Mist Flow : Part 2, Prediction of Droplet Transfer Rate
Transactions of the Japan Society of Mechanical Engineers, 1972 The liquid droplet transfer onto the duct wall was studied experimentally in the previous paper, part 1. In the present paper, a method for predicting the droplet transfer rate is proposed. The droplet transfer coefficient is expressed theoretically in terms of the duct height, the eddy diffusivity and scale of turbulent motion of droplet based on an ...
