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.

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.
3.10 TEST SET UP FOR TESTING
Fig.3.16 : Test Set Up
Figure 3.16 shows the schematic diagram of experimental setup used. 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.
