NUMERICAL SIMULATION OF FLOW MODELING IN DUCTED AXIAL FAN USING SIMPSON’S 3/8th RULE

The paper presents to develop the numerical simulation of flow model for three dimensional flow and one dimensional flow in Ducted Axial Fan by using the numerical integral procedure of Simpson's 3/8th rule. Main objective of this paper is to develop the numerical flow model and measure the pressure rise for varying the functional parameters of inlet velocity, whirl velocity, rotor speed and diameter of blade from hub to tip in ducted axial fan by using the code of MATLAB for Simpson's 3/8th rule. In this main phase of paper, the analogy of three dimensional flow and one dimensional flow of numerical flow modeling have been investigated to optimize the parameter of pressure rise in ducted axial flow fan by using Simpson's 3/8th rule.
