Description of the proposed heat release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The…

Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…

Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing due to increase in Energy Density. As the Scan Velocity decreases the temperature on workpiece surface will increase. This is because with the decrease in Scan Velocity, the Power Density increases, those results in more heat input. As the Beam diameter decreases…

Ferroelectricity Among the ferroelectric materials, the static dielectric constant depends on the temperature under the relation: Curie – Weiss relation: €r = P + Q/ (T-Tc), (T> Tc), P, Q are constants temperature independent. C = Curie constant Tc = Curie temperature A transition in phase is observed at temperature Tc. Above this, the material remains in Paraelectric phase (the phase where the elementary dipoles of different crystal unit cells are…

If your AC starts blowing hot air it may be due to the fact that it is freezing up. The coil is an important part of cooling your house up. The coils works by taking the warm air from your home and releasing them outside. If the coils in your AC unit become too cold they can freeze up. When your coils are frozen the ice can cause blockages, this results in you AC unit to run without cooling the home, whilst using a lot more electricity than usual. Why Do the Coils Continually Freeze Up? One…

Potential energy plays a big roll in a rollercoasters. All rollercoasters have the highest point or lowest point where the cart is at rest but either low or high. That is where potential energy is. Potential energy is the energy which results in position. Usually the most potential energy in a roller coaster is when it is about to start. The way that this type of energy is calculated and measured in P=MGH. M, being Mass, G being Gravity,…

Energy is measured in four different categories; calories, joules, kilocalories and kilojoules. Calories are the energy required to raise the temperature of 1 gram of water by one degree. A joule of energy is what it takes to move a mass of 1 gram at a velocity of one meter per second. For every one calorie there are 4.2 joules. A kilocalorie is the amount of energy to raise 1 kilogram of water by 1 degree. Kilojoules is the same a joules but it needs to be times by one thousand. The body needs…

Many people wonder what the best conditions are for growing crystals. Crystals are ordinarily made out of silicon dioxide molecules formed into an interlaced pattern ,or quartz, moreover sodium with chlorine ions interweaved (Science Line). Crystals are often found in mines everywhere, rocks, or even in your own home. These beautiful minerals are very intriguing. It is a worthwhile subject to research. My scientific question is in “In what temperature do crystals grow the longest ?”My hypothesis…

In comparison to the group work done for paper one, I do believe this was an improvement, mostly because we wrote the paper as we worked through the problem. This not only helped with preventing the procrastination of typing the paper at the last minute, but gave us time to gain an understanding of what was going in the problem by going to office hours. What I feel needs improvement is my the communication between my partner and I. partner initiative to understand the problem. There were times…
