| Abstract | ||
| This research is dedicated for analyzing the stability of system of flow equations for a delicate chip of a fluid exposed for medium heat ,where we found the growth of disturbance exist or not after making the system linearization it was shown through the results of analysis that these equations were in stable state when the real part of the wave velocity(α) is a negative quantity and it is unstable state when the real part of this velocity is positive quantity , We get stability and this happens when the Reynold's number is positive quantity i.e. R>0 . and when α>0 we get unstable state and this happens when the heat conductivity is a positive quantity. | ||
