Chapter 3 CFD Analysis of Radiator
3.1 COMPUTATIONAL FLUID DYNAMICS MODELING Computational fluid dynamics modeling was developed to predict the characteristics and performance of flow systems. Overall performance is predicted by breaking the flow system down into an appropriate number of finite volumes or areas, referred to as cells, and solving expressions representing the continuity, momentum, and energy equations for each cell. The process of breaking down the system domain into finite volumes or areas is known as mesh generation. The number of cells in a mesh varies depending on the level of accuracy required, the complexity of the system, and the models used. Equations solve for flow (x, y, and z velocities), energy (heat fluxes and temperatures), chemical reactions (reaction kinetics and species concentrations), and pressure based on various simplifications and/or assumptions (Anderson J. D. 1995). Some simplifications and assumptions are discussed below. If performed correctly, CFD modeling can accurately predict the performance of an entire system. 3.2 MODELING OBJECTIVE The primary goal of this CFD analysis is to predict a flow behavior of radiator with supporting velocity profile. CFD simulation is carried in 2 phases, viz. Phase 1: Geometry and Meshing 1) Geometry modeling will be done in Ansys Workbench 2) Meshing will be done in Ansys Mesher. a. Unstructured mesh is used for the analysis b. Fine mesh at specific location to capture the flow behavior. Phase 2: Steady State Simulation 1) Steady state incompressible simulation is perform for different flow and atmospheric condition 2) Flow and Heat transfer will be solved considering different working scenario 3) Appropriate turbulence model will be used depending on the Reynolds Number 1) Flow rates and pressure drops will be observed and verified
3.3 NUMERICAL MODEL DETAILS The commercial CFD Code Ansys Fluent was used as preprocessor for solving the flow physics. The computational Domain had to be represented as a finite volume model. Volume mesh is generated in Ansys Mesher and refinement is done at specific location to capture the flow behavior. Unstructured volume grid with 1375000 tetra-hydrel cells is used for the simulation. In Fluent putting appropriate scaling factors for scaling the mesh/geometry, and setting up the appropriate turbulence model, fluid properties, solver controls, convergence monitors. All simulations were performed using the Standard k-e turbulence model. For stability of the solution the linear upwind scheme was used in the beginning, once stabilized a second order upwind differencing scheme was used. 3.3.1 Boundary Conditions Inlet and Outlets: For the inlet and outlet the static pressure is specified, which is fixed to zero. Side and top walls, pressure outlet is considered. Porous Medium, the radiator is modeled as porous medium to account for the pressure drop in the radiator. Multiple Reference Frame (MRF) Zone, in a steady-state approximation in which individual cell zones can be assigned different rotational speeds. The flow in fan zone is solved using the moving reference frame equations.
Fig. 3.1 : Fluid domain for the radiator analysis Extended fluid domain is considered for the CFD analysis to capture the fluid behavior. The domain away from the radiator is open to atmosphere. The length of the domain is decided so that the flow near the fan and inside the radiator is not getting affected. Simplified radiator model shown above have fan, shroud and radiator with tubes. Radiator fan is rotating with different rpm is consider in the analysis.

In the graph L1 to L8 represent the line location as per the Fig. 3.4. Velocity trend is near about same for both CFD and experimental but the variation has been seen because of many assumption and measurement constraints. Radiator domain in CFD has tubes and remaining as a fluid domain, but in actual fins act as a resistance to the flow.

3.9 RESULTS & DISCUSSION CFD simulation for different revolutions of fan is shown in Figs.3.2, 3.5, 3.7, 3.9, 3.13, it can be observed that, 1. Velocity of air increases with the increase in rpm of radiator fan. 2. CFD and experimental velocity values are compared at different locations in Fig. 3.4 for 1500 rpm. 3. Fins are not considered in the simulation. It will also create some resistance to the flow. Radiator domain in CFD has tubes and remaining as a fluid domain. 4. Variations in the results obtained by CFD and experimentation are observed near about 15 to 20% at different locations. 5. It can be observed that average velocity of air entering before the radiator inlet at the center core is almost zero, and it increases towards the periphery, because of change in shape. (For proposed radiator with porous zone as shown in fig. 3.12) 6. Shape optimization can be done to improve the radiator efficiency i.e., i) Smaller fins are provided at the centre and length of the fins increases towards periphery. ii) Low velocity zones are created in the corners, hence eliminate corners and have circular radiator for optimum efficiency. 7. The new proposed radiator shape with porous zone is shown fig 3.12. 8. It is also observed from CFD analysis that, velocity of air increases from centre to extreme and further it remains constant. 9. Further it can be concluded that the air entering in the radiator, with new proposed design possesses almost constant velocity at the exit.

It consists of heaters, radiator, DC motor, anemometers, rotameters, infra-red temperature measuring gun, etc. Heaters are used to supply hot water to about 70 to 80 C to the radiator. Radiator is made for Maruti Alto design conditions which can be changed. DC motor is used to have the variable speed of the fan. Velocity of the air is measured at different points by using anemometer. Flow rate of water is measured by rotameter. Temperature at various points on the radiator is measured with the help of infra-red temperature measuring gun. 3.11 ACTUAL PHOTOGRAPHS OF EXPERIMENTAL SET UP
