Numerical and experimental analysis of vertical spray control patternators

Experimental and numerical modelling of nasal spray atomisation

Spray atomization is a common process found in different industries, where sprays under high injection pressure are widely recorded in the literature. Nonetheless, research on spray breakup mechanism under low pressure in pharmaceutical industry is still relatively rare. Numerical model in the Lagrangian approach was modified for simulating the spray formation from a nasal spray device in the c...

Experimental Analysis of a Vertical, Double-Effect Diffusion Solar Still

Simulation, Control and Experimental Analysis of 1,3Butadiene Purification Unit

Simulation of a process and analysis of its resulting data in both dynamic and steady-state conditions are fundamental steps in understanding the process in order to design and efficient control of system as well as implementing operational cost reduction scheme. In the present paper, steady and unsteady state simulation of Amir Kabir1, 3 butadiene purification units has been done by using Aspe...

Accurate Simulation of Low-Pressure Port Fuel and Water Spray in Internal Combustion Engines; Numerical and Experimental Study

One of the solutions to reduce pollutants and increase engine power is to use water spray in internal combustion engines. In this type of engine, fuel and water sprays play an important role in engine performance. In this regard, the purpose of this study is to accurately simulate fuel and water sprays and provide optimal coefficients to achieve the best simulation results. For this purpose, th...
