The military vehicle is mainly designed for surveillance purpose in areas where human excess is vulnerable and threatening. This is a multipurpose vehicle that can
-
Measure the distance and the angle with the help of a Radar.
-
Visualize obstacles by ultrasonic sensor.
-
Deliver constant video feedback of the surrounding environment with the help of a camera and
-
Remotely controlled by cellphones.
The vehicle was designed to serve the Military as it has a wide range of application in the corresponding sector.

Design of a Forced Draft Cooling Tower
Team members: Maruf Md. Ikram, Md. Azizul Hakim, and Md. Ali Noor Zaman.
Supervised by: Professor Md. Zahurul Haq, ME, BUET and Musanna Galib, ME, BUET.
Cooling towers are used to remove excess heat from power stations, chemical plants, domestic air conditioning units, etc. Here, we designed a forced draft cooling tower of height 3ft which is smaller than the commercially available ones. Thus, to increase the contact time between the air and the water, we used inclined flat mild steel plates with holes so that water covers a longer flow path and is turned into droplets. Choice of the material and the plate inclination angle are based on simulation-based iterative search. Later on, an experimental setup was constructed to assess the heat transfer performance. The study covers the determination of thermal load for variable
-
Feed flow rate
-
Rotational speed of the draft fan
-
Inlet and outlet water temperature and
-
Different environmental conditions.
Finally, a generalized computational model of the cooling tower had been designed in Ansys for the thermo-fluid system design lab to be used for similar future projects.
Two Cylinder SolidWorks Engine
Team member: Maruf Md. Ikram, Abrar Ul Karm, and Md. Ali Noor Zaman
In this work, a fully functional solidworks model of a two cylinder 4 stroke Compression ignition engine was developed for the CAD-CAM lab of the university. The engine consists of 973 parts in total. Starting from all the major components such as cam, cam shafts, push rods, crank shafts, intake and exhaust valves, etc. to the minor components such a bearings in the rotating parts, lub oil flow paths, water jacket, etc. are included in the model.
