Nuclear fuel recycle is a series of processes consisting of uranium ore mining, refining, conversion, uranium enrichment and conversion back into uranium metal. then converted into uranium metal fuel elements of nuclear through the fabrication process. Nuclear fuel is then fed into the reactor core and undergo reactions. At the research reactor is utilized neutrons produced in nuclear reaction, whereas in nuclear power reactors or heat utilized is the result of fission, which is used to convert water into steam which then drive the turbine-generator to produce electricity. Spent fuel removed from the reactor to be cooled for a while, then transported to the reprocessing facility. Elements of the remaining uranium and plutonium as a result of combustion sides separated to be used again. The chain of this process is called recycling Nuclear Fuel.

Electric cars are considered as the car of the future when the world’s oil reserves were running low. But the development of future cars is not the monopoly of major automotive manufacturers have already established. The students also contribute to developing this technology.

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished in generally considered to be an energy source that is either in relatively limitless supply, or that quickly regenerates when consumed.
The most common examples of renewable energy are solar power and wind power. For the purposes of human energy production, both of these resources are limitless; there will not be a scenario in the next billion years in which either sunlight or wind ceases to exist on Earth. Less common forms for renewable energy are biomass and biodiesel energy, both of which can be regenerated in a relatively short period of time (a term of months or years) by growing more plants. About 16% of global final energy consumption comes from renewable, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity. Read more

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. It is relatively cheap and sufficiently refractory even for steel foundry use. A suitable bonding agent (usually clay) is mixed or occurs with the sand.
Sand casting is used to make large parts (typically Iron and Steel but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). Read more

Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and logarithms to solve and analyze problems that include fluid flows. Using computers to do millions of calculations to simulate the relationship between fluid and gas to the surface in the engineering complex.
However, even with simplified equations and high speed supercomputers, only approximate solutions can be achieved in many cases. More accurate codes that can accurately and quickly simulate even complex scenarios such as supersonic or turbulent flows are an ongoing area of research. Validation of such codes is often performed using a Wind tunnel
Computational fluid dynamics constitutes a new “third approach” in the philosophical study and development of the whole discipline of fluid dynamics. In the seventeenth century, the foundations for experimental fluid dynamics were laid in France and England. The eighteenth and nineteenth centuries saw the gradual development of theoretical fluid dynamics, again primarily in Europe. Read more

We have demonstrated earlier with reference to the heat engine that, even under ideal conditions, a heat engine must reject some heat to a low-temperature reservoir in order to complete the cycle. That is, no heat engine can convert all the heat it receives to useful work. This limitation on the thermal efficiency of heat engines forms the basis for the Kelvin–Planck statement of the second law of thermodynamics, which is expressed as follows

The second law of thermodynamics, which asserts that processes occur in a certain direction and that energy has quality as well as quantity. A process cannot take place unless it satisfies both the first and second laws of thermodynamics.
