Hello Everybody, Im doing my lab report on Fatigue testing for a Single Edge Notched Tension (SENT) sample and need to plot ΔK vs da/dN for a series of a vs N readings at different R and maximum stress values (attached in the picture). I've just been given one equation for Ki and told that I...

I have also attached the simple code of matlab. cpL = 4186; kL = 0.564; rho = 1000; temp_melt = 0; latent_heat = 333400; temp_source = 25; time_total = 12600; alp_L = kL/(rho*cpL); dT = temp_source - temp_melt; stephan_l = (cpL*dT)/latent_heat ; time_latent = [0:1:time_total]; x = 0.01...

Hello, I am a student in Coventry, UK working on Phase Change Problems and going through 1-Phase Neumann Analytical solutions. As per most books, or specifically Mathematical Modeling of Melting and Freezing Processes chapter 2 (attached) page 36, equation 15, the general equation of...

I am trying to make a spirally fluted pipe in ANSYS. I made the cross section as in the attached figure and sweeped on a straight line perpendicular to plane of the cross section. However I get a sort of a drill bit instead of the required spirally fluted pipe. Is there an issue with the cross...

hey there can anyone give me research paper or tell me the mathematical equations that govern a fluidyne pump. specifically if i want a required power output how to calculate 1) the heat input required 2) the dimensioning required of the displacer and tuning columns 3) predict the motion of...

yes i viewed some of those videos. i plan to operate a pump using this engine but at the moment i am constructing a small prototype version. it is running but not that smoothly as expected. i wanted to ask about the allowable variation in the diameter and lengths of the tubes used ??

very nice link mate. very informative. i hope u will help me if i have any problems while constructing it. thank u

Can anyone help me in constructing a basic fluidyne engine to pump water. is the dimensioning of the tubes etc critical. any link/person can help me regarding this ??

do u have any links or pics related to this stuff ??

does anyone know how the rollers and motors are place in the U-shaped part of a curved conveyor belt used in airports?? any links or pics would be appreciated ??

Does anybody know where i can find the Digital Circuit for an ATM Device in .ewb format??
