In the field of non-destructive evaluation (NDE), the newly developed distributed point source method (DPSM) is gradually gaining popularity. DPSM is a semi-analytical technique used to calculate the ultrasonic fields (pressure, velocity and displacement fields) generated by ultrasonic transducers of finite dimension immersed in homogeneous or non-homogeneous media. In this report the technique is extended to model the transducer immersed in triple layered non-homogeneous fluid and the propagation of steady & transient wave and its pressure generated with transducer is placed at both normal and non-normal angles. And Tone burst signal is used as input signal at one end of fluid and reflected as well as transmitted pulse is observed at various points. The results obtained from DPSM modeling are compared with experimental results for both homogeneous and triple layered non-homogeneous fluid and the results of DPSM are following the same pattern as the experimental results.
