Determine physical properties of an organic citric acid (processed lime juice) dissolve with water using experimental apparatus

This paper describes experimental studies on the physical properties of processed lime juice to dissolve with water. Lime juice as known as organic citric acid have many advantages in our life especially in food industries, pharmaceutical industries, anticancer and antioxidant and cleaning agent. Physical properties of liquid include pH, viscosity, density, molar mass and surface tension. This Study conducted using common laboratory apparatus such as Pycnometer, the pH device (HI 9811 pH), Viscolite700 etc. The additional organic citric acid by percentage in water was changed the physical properties of liquids. The future strategy of this research is to introduce organic lime juice mixed with water in spray system as cleaning agent, reduce air pollution and reduce water consumption for Commercial Restaurant Equipment

Characteristic study of flat spray nozzle by using Particle Image Velocimetry (PIV) and ANSYS simulation method

Water mist sprays are used in wide range of application. However it is depend to the spray characteristic to suit the particular application. This project studies the water droplet velocity and penetration angle generated by new development mist spray with a flat spray pattern. This research conducted into two part which are experimental and simulation section. The experimental was conducted by using particle image velocimetry (PIV) method, ANSYS software was used as tools for simulation section meanwhile image J software was used to measure the penetration angle. Three different of combination pressure of air and water were tested which are 1 bar (case A), 2 bar (case B) and 3 bar (case C). The flat spray generated by the new development nozzle was examined at 9cm vertical line from 8cm of the nozzle orifice. The result provided in the detailed analysis shows that the trend of graph velocity versus distance gives the good agreement within simulation and experiment for all the pressure combination. As the water and air pressure increased from 1 bar to 2 bar, the velocity and angle penetration also increased, however for case 3 which run under 3 bar condition, the water droplet velocity generated increased but the angle penetration is decreased. All the data then validated by calculate the error between experiment and simulation. By comparing the simulation data to the experiment data for all the cases, the standard deviation for this case A, case B and case C relatively small which are 5.444, 0.8242 and 6.4023

Study the velocity and pressure exerted in front of the filter surface in the kitchen hood system by using ANSYS

Commercial kitchen hood ventilation system is a device used to capture and filtered the plumes from cooking activities in the kitchen area. Nowadays, it is very popular in the industrial sector such as restaurant and hotel to provide hygiene food. This study focused at the KSA filter part which installed in the kitchen hood system, the purpose of this study is to identify the critical region which indicated by observing the velocity and pressure of plumes exerted at of KSA filter. It is important to know the critical location of the KSA filter in order to install the nozzle which will helps increase the filtration effectiveness. The ANSYS 16.1 (FLUENT) software as a tool used to simulate the kitchen hood systems which consist of KSA filter. The commercial kitchen hood system model has a dimension 700 mm width, 1600 mm length and 555 mm height. The system has two inlets and one outlet. The velocity of the plumes is set to be 0.235m/s and the velocity of the inlet capture jet is set to be 1.078m/s. The KSA filter is placed 45 degree from the y axis. The result shows the plumes has more tendency flowing pass through at the bottom part of KSA filter

An investigational research of spray pattern for deflector flat spray nozzle using horizontal patternator

Valuation of the spray patterns and spray angle is necessary for producing nozzle applications such as in combustion process, agriculture, which is the experiment result in less liquid usage, and increased spray distribution accuracy. Therefore, this study investigate to analyze the spray distribution nozzle and consider the water consumption and spray angle using several type of deflector flat spray. First, the result should assist with spray patternator construction to determine water consumption. Then, measure of spray angle using Digital Single Lens Reflex Camera (DSLR) and image J software. The results provided support two fluid flow in the nozzle with increase of air pressure can reduce water consumption compared with single fluid flow. Effect of relationship between air pressures with water pressure in the nozzle producing the large spray angle compared water pressure only in the nozzle. Thus, fluid pressure in the nozzle is main parameter in developing on spray distribution. Spray pattern and spray angle are also an important consideration in nozzle selection and application
