The Design of Appropriate Technology of an Egg Tray Machine
  • Abstract
  • Keywords
  • Reference
  • Full Article
Managing fibrous waste such as paper into useful packaging materials can help reduce large amounts of paper waste. Laboratory-scale appropriate technology machines were developed to print paper pulp into egg trays by means of suction. The pulp-making process includes collecting waste paper, sorting according to paper grade, pulping, egg tray making and the final process is sun-drying. The machine consists of a mould, a slurry container and an electric mechanism to operate the machine. The machine works on the principle of suction with a pulp slurry consistency of about 5%.

Padma River Bank Erosion in Naria, Shariatpur District, Bangladesh: Geomorphological, Geological, and Geotechnical Aspects
  • Abstract

  • Reference
  • Full Article
The Naria Upazila of the Shariatpur district is situated on the right bank of the mighty Padma River, where extensive riverbank erosion has been occurring over the past several years. The purpose of the study is to decipher the geomorphological, geological, and engineering geological causes of bank erosion in the area. Conventional fieldwork was carried out in the area and systematic sample collection was done. Standard laboratory processes were followed to analyze the samples. The aerial photographs and Google images study indicate that the Tippera alluvial sediments of the Mid-Holocene age are less eroded than the active bar and floodplain deposits of recent age.........

Computational Fluid Dynamic Analysis of Ahmed Body in Martian Environment
  • Abstract
  • Keywords
  • Reference
  • Full Article
This research work presents the computational aerodynamic study of Ahmed body situated in Martian environment in comparison with Earth's environment. The hybrid RANS-LES model with the dynamic Smagorinsky-Lilly method is used to capture flow characteristics of the wake region of Ahmed body. A comprehensive mesh independence study is conducted to obtain the results, which are approximately unaffected by mesh resolution. The impact of three critical variables i.e., slant angle, stream velocity and temperature is analyzed on flow behavior. It is observed that the difference in Martian and Earth environment have considerable effect on coefficient of drag experienced by the Ahmed body. It is also found that the slant angle plays a vital role in aerodynamic performance of Ahmed body. A noticeable difference in coefficient of drag is observed by changing the temperature for........
