NUMERICAL AND EXPERIMENTAL INVESTIGATIONS ON THE INFLUENCE OF SURFACE MODIFICATIONS INTEGRATED WITH VORTEX GENERATORS ON NACA0010 AIRFOIL

Srijan Dasgupta; Kazi Afzalur Rahman; Md. Kawsar Sajib; Md. Ibrahim Khalil Tanim (Department of Mechanical Engineering, 2022-10)

Vortex generators and surface modifications are done to reduce the wake region and increase the aerodynamics efficiencies of an airfoil. The performance test of NACA0010 airfoil with various types of surface modifications ...
PERFORMANCE ANALYSIS OF R32/R600a BLEND WITH TiO2/MO NANOFLUID FOR EXISTING RESIDENTIAL AIR CONDITIONING SYSTEM

Ahmed, M. I.; Ahamed, J. U.; Razzaq, M. E. A. (Department of Mechanical Engineering, 2022-10)

This experimental study investigated the energy and exergy performance of R32/R600a (50:50 by mass) with TiO2 nanofluid for a residential air conditioning system which was originally designed for R22. R32/R600a has ...
PRIORITIZING THE FACTORS INFLUENCED PARTICULATE MATTER EMISSION APPLYING FUZZY TOPSIS

Zerin, N.H.; Sayem, A.S.M. (Department of Mechanical Engineering, 2022-10)

Particulate matter (PM) is a key component of ambient air that has a significant influence on climate change and is harmful to human health. Particulate matter in the high atmosphere affects the earth's radiation, cloud ...
SYNTHESIS AND CHARACTERIZATION OF TiO2 AND ZnO NANOPARTICLES

Das, U. D.; Ahamed, J. U.; Hossain*, M. A. Mowazzem; Razzaq, M. E. A.; Dewanjee, S.; Jisu, R. N. (Department of Mechanical Engineering, 2022-10)

In this experimental study, TiO2 nanoparticles were synthesized using an ultrasound-assisted method, while the ZnO nanoparticles were fabricated using a chemical precipitation method. Results of X-ray diffraction ...
EFFECT OF WHEEL ALIGNMENT, SPEED AND ROAD CONDITION ON FUEL EFFICIENCY OF A LIGHT-DUTY VEHICLE

Das, R. K.; Hossain, M. A. Mowazzem; Islam, M. T.; Banik, S. C. (Department of Mechanical Engineering, 2022-10)

The fuel efficiency of a TOYOTA ECHO PLUS-2ZZ-GE-02 model light-duty vehicle was investigated experimentally based on the wheel alignment system. The light vehicle has been analyzed with the variation of vehicle speed ...
NUMERICAL AND EXPERIMENTAL INVESTIGATION OF WAVE ENERGY HARVESTING THROUGH BUOY EFFECT

Hai, T. B.; Rahman, M.; Kabir, S. S.; Askary, M. A. H. A.; Rahman, Md. Arafat (Department of Mechanical Engineering, 2022-10)

Wave energy is a reliable source for power production from the perspective of certainty. The study focuses on determining an appropriate buoy structure of specific material to develop a mechanism to harvest wave energy ...

A REVIEW ON HYDROCARBON (HCs) AS AN ALTERNATIVE REFRIGERANT: BASED ON THERMODYNAMIC AND ENVIRONMENTAL APPROACH

Razzaq, Moham Ed; Ahamed, Jamal; Hossain, Mowazzem; Hossain, S. (Mechanical Engineering Research Journal, 2019-03)

This review paper present the possibilities of using hydrocarbons in the cooling and heating purposes in the vapor compression system are discussed elaborately. Different types of hydrocarbons (HC) as alternatives in terms ...
ENHANCEMENT OF HEAT TRANSFER OF WATER FOR TURBULENT FLOW THROUGH TUBE USING U-CUT TWISTED TAPE INSERTS

Razzaq, Moham Ed; Hossain, M.A.M; Ahamed, J.U. (Department of Mechanical Engineering, Chittagong University of Engineering and Technology, 2016)

In this experiment tube side heat transfer coefficient, pressure drop, friction co-efficient and percentage of increase in those parameters for water using U-cut twisted tape inserts into the tube were measured. The test ...
