About Stephen


Bio

I have about 3 months experience as a teaching assistant for a course called, "Intro to Solidworks". Currently I have about 4 years of design experience. I have worked as a Design Engineer for a little over 2 1/2 years now in industrial applications. Also I worked as a Solidworks Designer for about 1 1/2 years designing custom radiators.

Solidworks

I believe I know Solidworks very well, working with the program professionally. I also was a teaching assistant for the Solidworks course in my undergraduate. I worked as a Solidworks Designer for about 1 1/2 years designing custom radiators.

Sample: Material Selection for high temperature components: 1.) Write a two-page article outlining the types of material used in the following applications: a.) Jet engine Housing The jet engine housing materials needs to be lightweight, strong, corrosion resistant and thermal stable. One of the major materials that are used in the jet engine is titanium which has excellent weight ratio and resistance to extreme heat. Ceramic matric composites such as SiC/SiC are excellent materials for a jet engine. b.) Jet engine combustion chamber During combustion temperatures can reach up to 2100 C. Most metal melt at 1600 C. The combustion liner is lined with ceramic thermal coatings to offer excellent heat resistance. The ceramic coatings tend to reduce temperatures by about 300 C. Combustion chambers have holes between the bypass and the combustion chamber to allow for film cooling on the combustion liner. A titanium alloy is typically used for its excellent ductility properties. c.) Jet engine turbine blades Jet engine turbine blades are exposed to a maximum of 850 C to 1700 C. The turbine blades are subjected to centrifugal forces and fluid forces that can cause fracture, wielding and creep. Nickel based super alloys tend to be used in turbine blades due to the excellent weight to strength ratio at high temperatures. Turbine blades tend to have thermal barrier coating to increase creep and fatigue resistance by improving the oxidation and corrosion resistance. Ceramic matric composites can be used in turbine blades such as SiC/SiC composites. Turbine blades also have cooling advanced cooling passage to increase fatigue life due to the high temperatures. d.) Piping in steam lines of power plants Steam lines of power plants typically see a temperature of a maximum of 600C. In addition, the pipe will most likely be pressurized. The piping needs to be able to resist corrosion. Stainless steel should be used to prevent rusting. Also Stainless steels have high strength at elevated temperature. e.) Fuel rod cladding in pressurized water reactor The cladding of the fuel rods must withstand the water and the nuclear fuel. The cladding must be made of corrosion-resistant material with low absorption cross section for thermal neutrons. Stainless Steel can be used as cladding. Zircaloy is used because of the low absorption of thermal neutrons, high hardness, ductility, and corrosion resistance. f.) Heat exchanger tubes in power plants An important parameter for heat exchanger tubes are to ideally be high “heat sink” materials such as Copper and Aluminum. If the temperatures are low copper is a good choice for tubbing as long as the design accounts for wall thinning for copper tubing. As power plants, the temperature that the tubbing experiences may be high. Depending on the temperature, the piping may need to be made of Stainless steel. Stainless steel is good as preventing corrosion. Galvanic corrosion will be important in the fluid medium is not water. g.) First wall in fusion energy system The first wall is subjected to high energy density radiation and high doses of high energy helium implantation. The material must also withstand high temperatures and withstand cyclic thermos-mechanical stresses. Helium implantation rates can result in blistering and exfoliation of the fist wall material. The instantaneous heater is equal to 2X1016 W/cm3 at ?t=2 µs and large ion implantation rates of 7X1016 He/cm3 per shot. Tungsten may be a good choice due to its high temperature stability. Beryllium is a good choice due to its excellent plasma-contamination properties and its high thermal conductivity for thermal management. h.) Re-entry vehicle Thermal Protection System One type of Thermal Protection system is an Ablative heat shield where the extreme heat fluxes consumes the material thru pyrolysis. One heat shield is PICA which is a carbon fiber preform impregnated in phenolic resin. Another type of Thermal Protection System is the insulated ceramic tiles that were used on the Space Shuttle. The tiles are ceramic and insulate the main aluminum body from the temperatures of re-entries. The nose of the space shuttle used C/C composites due to the high temperatures and loading. Thermal Protection Systems are use high temperature CMC’s such as C/C, C/SiC, and SiC/SiC.
