    In recent times, the gear design has become a highly complicated and comprehensive subject. A designer of a modern gear drive system must remember that the main objectives of a gear drive is to transmit higher power with comparatively smaller overall dimensions of the driving system which can be constructed with minimum possible manufacturing cost, runs reasonably free of noise and vibrations and which requires little maintenance. As a result, an interactive user friendly low cost software HelOSpur2011” was developed to relieve designer of analytical way of calculating needed parameters for design of helical and spur gears, generating reliable data for use in manufacturing process. The software is able to produce accurate and efficient 2D (two dimensional) and 3D (three dimensional) detail working drawings as a result of interactive computer graphics and provide substantial saving in time and cost of production. Results generated by the software shows that the computed face width (for strength check) and wear check for helical gears design as against manual methods were in relative error of 0.64% and 0.35% respectively. Relative accuracy of the software stand at 99.6%.The work has demonstrated the effectiveness of using the software to cater for helical gear design problems as well as spur gears when helix angle is zero. The introduction of this software to the society will in no small way increase productivity and reliability of helical and spur gears design.

    DEVELOPMENT OF COMPUTER PROGRAM FOR DESIGN OF A SCALABLE COMBUSTION FURNACE USING PALM KERNEL SHELL AS HEAT SOURCE
    (Faculty of Engineering Hunedoara, Romania, 2017-03-01) .K.O. OLADOSU; B. KAREEM; B.O. AKINNULI; T.B. ASAFA
    Steam boiler is an integral and important component of steam turbine used for electricity generation. Its design is however complex, time consuming and prone to errors if done manually. In this study, we report the application of computer based approach to design palm kernel shell combusting furnace for generating a desired amount of electricity. Using backward calculation approach, standard design equations were used to size furnace and its components. The equations were coded and solved using C-Sharp programming language. The results showed that to generate 5 kW of electricity from palm kernel shell; 5.5 kW turbines, 3.6 m super heater, 3.2 m riser, furnace of 1.432 m height and 0.45 m3 volume were required having considered power loss due to friction and others. While these results are in good agreement with those calculated manually, human errors are virtually eliminated. In addition, calculations and drafting time were reduced from 5 hrs 47 mins when done manually to about 4 mins when the developed code was used. This code can be used to size boiler for any desired power output.
