NPTEL-Fluidization Engineering July 2023 Problem solving session-Week 1

Fluidization Engineering Problem solving session Week 1 for the NPTEL course by Prof. Subrata K Majumder Note: There was a confusion in the video, I have given a wrong answer for a question. For the question Q25, In the case of homogeneous or particulate fluidization (a) As the gas velocity increases, the bed expands smoothly in a homogeneous manner (b) Further increase of gas velocity, bubbles are formed in the bed (c) Both (a) and (b) (d) None of the above The right answer is: (c) Both (a) and (b), because when the gas fluidizes homogeneously as in particulate fluidization, the bed expands smoothly. But with further increase of gas velocity, the bubbles start to form in the bed.
