Abstract An experimental study on the effect of sidewalls on the flow characteristics of a three-dimensional turbulent square wall jet is carried out at a Reynolds number of 25,000. The sidewalls are defined as the two parallel plates along the vertical jet centerline. Four different sizes of sidewall enclosure (here after referred to as SWE) are placed at the lateral positions (z) of ±3.5h, ±4h, ±4.5h and ±5h from the vertical jet centerline plane, where h is the height of square jet. The mean characteristics of fluid flow in wall normal (y) and lateral (z) directions at different downstream locations (x/h = 0.2 - 45) are measured using a hotwire anemometer. The velocity measurements are also performed in the z ? y lateral plane at four downstream locations (x/h = 30, 35, 40 and 45). Results indicate that the mean velocity profile in lateral and wall normal directions behaves differently depending on the size of SWEs. The decay rate of mean velocity increases with decrease in size of SWEs after the downstream location (x/h ≥ 20). The decay rate of the maximum mean velocity increases about 5% in 140mm SWE as compared to 200mm SWE. It is noted that spread of the jet in wall normal and lateral directions increases with decrease in size of SWEs after the attachment of the flow stream on the sidewalls. In the present case, the smaller size of SWE (140mm SWE) has 14.3% and 26.2% higher spread rate as compared to larger size of SWE (200mm SWE) in wall-normal and lateral directions, respectively. It is also seen that the self similar profile gets delayed in wall normal direction as compared to lateral direction for all the cases. The wall normal self-similar profile is obtained early with increase in the size of SWEs and it is obtained at x/h = 30, 27, 24 and 20 for 140mm ,160mm,180mm and 200mm SWEs respectively. The flow stream seems to climb the sidewall and this tendency increases with increase in size of SWEs.
