THERMAL ANALYSIS-CONVECTION FILM COEFFICIENT

Submitted by anand m on

My thermal simulation in the alternator required convective coefficient . Presently i have computed convective coefficient for stator,rotor,rectifier assembly by thermal testing at steady state condition. I have completed thermal simulation for these components of the alternator . Next, i want to perform thermal simulation for entire alternator.Is there anybody, provide me guidance to formulate correlation between geomentry,ambient condition,convective flim coefficient.Further, i have to model contact among components in the alternator. it requires thermal contact conductance.

Complex numbers in structural dynamics

Submitted by Stefan Szyniszewski on

Dear All,

Can you recommend a book, which introduces complex numbers in the context of
structural dynamics? 

It seems that recasting differential equations with unknown acceleration,
velocity and displacement in the complex number format helps to arrive at the
solution. It seems indispensable when dealing with damping.

I am looking for a resource that formulates dynamic equations of motions
using complex numbers, with step-by-step explanations.

Your advice and thoughts will be appreciated.

Thank you,

Stefan
