| Abstract: | The natural convection phenomena from a horizontal heated tube is investigated using Vintens ESPI, Video holographic interferometry and holography. Three different optical arrangements and the principle of gas temperature measurement are described. The experimental results obtained from the above techniques are compared with those from thermocouples. The comparison shows that they are consistent with each other. The sources of error which may affect the measurement are discussed and estimated qualitatively. |
