Optimization of Inlet ducts
for Server Room Cooling System |
The
server room cooling system consists of four air handling
units, which supplies cold air to the room through
ducts. The Capacity of all the air handling units is not
the same, due to which the cold air entering the room is
not uniformly distributed. The aim of the project was to
optimize the profile and the number of baffles such that
the flow is uniform at the duct outlets and also
automate the geometry, mesh generation & solver
processes for a 2D Case with Multi-file handling and
C-Programming.

Modeling Of Automotive
Diesel Engine At Various Fuel Injection Times To
Analyze Forthcoming Emission Norms |
This
project consists of modeling and analysis of diesel
engine for various fuel injection times using FLUENT
6.2.16 which is implemented in a full cycle of
engine. GAMBIT 2.3.16 was used as the preprocessing
tool. In this project, domain was divided into
several fluid zones. Few zones were meshed with
quadrilateral elements and the remaining zones with
triangular elements. Further, the area above the
valve has non-conformal interfaces. Unsteady
segregated solver along with k-epsilon turbulence
model was used. Discrete Phase Model was employed
for simulating the fuel injection, evaporation, and
droplet boiling. Analysis of the results for various
injection times was done by post processing.
Following steps were followed during this project:
|
|
Build the required geometry and mesh it with tet
and quad elements in GAMBIT. |
|
|
Define unsteady segregated solver, k-epsilon
viscous model, injection model and boundary
conditions |
|
|
Defined grid interface and dynamic mesh
parameters, events and zones for mesh motion |
|
|
Analyzing the results for various fuel injection
timing in the FLUENT solver |

CFD Analysis of
RMF (Raised Metal Floor) Data Center |
The deployment of computer systems in large
number and in very dense configurations in data
centers has resulted in very high power
densities at room level. Due to such high heat
loads, designing an Air-conditioning system for
a data center using simple energy balance is no
longer adequate. Moreover the data center design
cannot rely on intuitive design of air
distribution. It is necessary to model the
airflow and temperature distribution in a data
center.
Our modeling focus is to locate "Hot spots" and
it is equally important to analyze the airflow
and temperature inside each server rack and for
the overall room.

CFD Analysis of
Climate Control Seat |
Project involves design and optimization of
Climate Control Seat (CCS). The CCS consists of
Thermoelectric Cooling (TEC) unit fixed under
the car seat. Depending on occupant's
requirement hot or cold air is supplied through
channels from the TEC unit to the CCS. GAMBIT
and FLUENT were used for modeling and analysis
of air the flow and temperature distribution of
the CCS. For this analysis, porous media model
from FLUENT was used. Based on the results, air
distribution channel locations were fixed.

CFD
analysis for "Automatic climate control
for passenger car HVAC" |
In extreme
climatic conditions, to create and
maintain a comfortable indoor climate
for all occupants in a car is difficult
and a critical task in car HVAC design.
Controllable parameters which influence
the indoor climate are the inlet air
temperature, and the distribution of
air. If the temperature of the human
body surface is monitored, the inlet
temperature condition can be changed
accordingly so as to control temperature
in the car. This project was aimed to
simulate such kinds of flow. User
Defined Function (UDF) in Fluent was
used to monitor the temperature on the
human body surface. The project was
carried out in the following way:
|

GAMBIT 2.3.16. |
