Abstract

Batteries or accumulators on the car serves to store electrical energy in the form of chemical energy, which will be used to supply the system to the electric starter, ignition system, lights and other electrical components. In the car, the battery damage can occur due to many factors including temperature. Batteries that work at higher temperatures will have a life span that is lower than at normal room temperature (25OC). Generally, the location of the battery is in the engine room so that the battery position was close to the engine. The car engine works at the optimum temperature 80 ° C - 90 ° C so that the heat is around the engine room can be exposed directly to the battery and can affect the performance and lifetime of the battery. Adding insulation on cover, with low thermal conductivity coefficient will decrease heat transfer rate . Polyurethane as insulation with 7,5 mm thickness will maintenance battery liquid temperature 45,5 OC after running through three hundred minutes.

Abstract

Many previous studies of ejector have been conducted to understand and maximize the ejector performance. The study can be in form of experiments, analytical, and numerical simulation. The numerical simulation looks for the most effective and efficient effort and time in modeling flow process inside the ejector. Model simplification becomes one of solution in conducting simulation effectively. Three dimensional models in general are applied to an ejector that would be analyzed. These models can be compared to the simpler model, namely axisymmetric 2D model. The current study investigated the comparison between 3D and 2D models using numerical solution. Three types of ejectors from different application were used as the objects of the study. The analysis was conducted by comparing the qualitative and quantitative results. The results show that qualitatively the 2D axisymmetric model has good comparison to the 3D model. Quantitatively, 2D axisymmetric model has good similarity to 3D model for ejector performance parameters, such as entrainment ratio and Mach number with biggest difference of 5.7%. However, the velocity and pressure distribution have bigger discrepancies at both axial and radial directions at the area with extreme change, such as at throat nozzle. It can be concluded that the 2D axisymmetric model can be used as substitution of 3D model when the objective is only to obtain ejector performance and qualitative study.

Abstract

The use of the tank as well as a container or tank of liquid reserves to make use of the tank as a necessity. By using its own tank design model which is technically very possible to make the pressure in the tank is less than atmospheric pressure so that the tank will take some role pump connected in series are used for the purpose of improving high pressure. Thus the pressure in the tank is smaller than the atmospheric pressure is only generated from the process flow itself will save pump power required on the press. To prevent the air pressure in the tank exceeds the atmospheric pressure relief valve on the tank supplied air to the atmosphere. The more water into the tank, the greater the downward thrust force due to the weight of water and by the buoy to the piston in fixed position, the tank will move downward relative to the piston. The pressure in the tank due to the movement of the closed tube will follow the phenomenon of negative pressure. To get a larger volume of air or spring difleksi rate greater then the pole float should be as light as possible and frictional forces as small as possible.The goal is to produce a prototype tank that can lighten the pump working in particular on the discharge side so it can be input pump power savings. The calculations show that a high hit on the side of the press can be reduced upto 100 percent even including reducing losses on the discharge side by enlarging the capacity of the tank. Thus happen electricity savings of the power required on the discharge side of the pump to drain the water into the tank. With spring replacement inverting the inversion moment will produce a higher pressure suction force behind the rise of the spring.
