Aluminum is the most widely used metal in industry. Aluminum smelting is one of the important steps that needs to be carried out to produce products made of aluminum metal with good quality. In the process of smelting aluminum there are several problems that occur, one of which is the growth of corundum in Si C refractories which affects the quality of aluminum melt and the durability of Si C refractories. This research was conducted to see the heat transfer in Si C and the effect of the presence of Corundum on heat transfer. This research was carried out by …
Origami: Numerical Solutions Of Apparent Absorptivity In Origami Folds, Michael Farnsworth, Brian Iverson
Origami: Numerical Solutions Of Apparent Absorptivity In Origami Folds, Michael Farnsworth, Brian Iverson
Journal of Undergraduate Research
There are three major types of heat transfer: conduction, convection, and radiation. In many cases, radiation is ignored due to the fact that the amount of heat transferred by this method tend to be small compared to conduction and convection. However, in space and in some settings on earth, radiation is dominant and important. Absorptivity is a measure of an object’s ability to absorb radiation, and apparent absorptivity is a measure of how the shape of an object affects the amount of radiation that it absorbs. For example, if you were to shine a flashlight on a mirror, the light …
Modeling And Computation Of The Maximum Braking Energy Speed For Transport Category Airplanes, Nihad E. Daidzic
Modeling And Computation Of The Maximum Braking Energy Speed For Transport Category Airplanes, Nihad E. Daidzic
Journal of Aviation Technology and Engineering
Transport-category or FAR/CS 25 certified airplanes may occasionally become braking energy capacity limited. Such limitation may exist when heavy airplanes are departing airports at high-density altitudes, on relatively long runways, and/or possibly with some tailwind component. A maximum braking energy VMBE speed exists which may limit the maximum allowable takeoff decision/action speed V1. The ever-existing possibility of high-speed rejected takeoff in such conditions may also limit the airplane gross weight for declared available distances. To gain deeper insights and acquire better understanding of the topic, a theoretical model of the maximum braking energy and the related VMBE speed for T-category …
An Analytical Model For Heat Transfer Through A Thermoelectric Device Used In Waste Heat Recovery, Zachary Smith, Dr. Matthew Jones
An Analytical Model For Heat Transfer Through A Thermoelectric Device Used In Waste Heat Recovery, Zachary Smith, Dr. Matthew Jones
Journal of Undergraduate Research
A considerable amount of energy that is produced in a typical power generation process is rejected to the environment as low-grade waste heat. This heat is rejected at a temperature that is difficult to efficiently convert into electricity. One promising method of recovering this waste heat is through the use of thermoelectric generators (TEGs) that operate by means of the Seebeck effect. Effort has previously been placed in predicting the power output of TEGs. With knowledge of the temperature differential across a thermoelectric device and the properties of the electrical components the device is connected to, the electrical power output …
