Hello, and good day… <\/p>\n

I want to determine the temperature (T) of the NiTi wire with different lengths of 100, 200, and 300 mm. I used steady-state thermal-electric conduction in Ansys Workbench and added this command (antype,4) to get the transient analysis with time. I found the temperature was different by changing the diameter of the wire, but it was still the same for different lengths. What is wrong, please?<\/p>\n

I used the convection coefficient (h) =5 W\/m^2-C for the surface of the wire and applied a 1A current through the wire (by adding v = 0 on one side and A = 1 for the opposite). The specific heat values are 320 J\/kg-°C, thermal conductivity is 18 w\/m-c, resistivity (ρ) = 8 x 10-5 Ω-cm, and density is 6450 kg\/m3.<\/p>\n
