Development of the Metal Foam Electrical Resistance Heater. (Under the Direction of Dr. Albert Shih.) This thesis presents a novel concept using a radial heating element made from porous Fe-Cr-Al metal foam in an air heater. Electrical resistance heating has been used extensively to convert the electrical energy into thermal energy. An analytic heat transfer model is first developed to estimate dimensions of the heating element. Four prototype Fe-Cr-Al metal foam electrical heaters with different

the fact that there are many companies that are affected of the global economic crisis. And the least thing that you can do about unemployment is to find a best way on generating money like you can accept laundry services‚ plumbing services‚ or electrical repair services if you are skilled enough to do the job. Then‚ you could start a certain profitable business like food house or a small store that does not require you much capital so that you will not find it hard to save enough money from the

Calculating generator reactancesPower topic #6008 | Technical information from Cummins Power Generation Calculating generator reactances > White paper By Timothy A. Loehlein‚ Technical Specialist-Electrical Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order

1. Introduction to Power Engineering 1.1 Power System Functions The traditional power system is arranged as a hierarchy. Generators feed into a high voltage transmission system that facilitates bulk transfers of power over large distances. Connected to the transmission system are medium voltage distribution networks that take power from grid supply points and deliver it to the customers who are supplied a low voltage. For a lot of its history‚ the electricity supply industry has operated as

The use of electrical stimulation has been used widely in physical therapy for many different reasons to treat and manage pain‚ joint limitations‚ spasticity and spasms‚ muscle disuse atrophy‚ circulatory deficits and muscle re-education. The purpose of this case report is to describe the efficacy of using a medium frequency alternating current (MFAC)‚ a Russian stimulation‚ for muscle re-education and strengthening to the quadriceps femoris muscles to help improve the ability to perform sit to stand
