Drying kinetics of sour cheery is investigated in solar dryer with forced convection and under open Sun with natural convection. Drying data were fitted to different mathematical models, whose performance was investigated by comparing coefficient (R), reduced chi-square (Ç) and root mean square error (RMSE) between the observed and predicted moisture ratios. Among these models, drying model dev...

A numerical simulation study was carried out to investigate a steady two-dimensional laminar natural convective heat transfer from uniformly heated inner circular cylinder placed inside an air-filled square enclosure with porous material. The enclosure’s side and upper walls were isothermal, while the bottom wall adiabatic. All calculations performed in range of Rayleigh numbers between 103 107...

This paper is focused on the application of hybrid Single relaxation time lattice Boltzmann and finite volume methods in conjunction with discrete ordinates method to simulate coupled natural convection and volumetric radiation in differentially heated enclosure, filled with an absorbing, emitting and non-scattering gray medium. In this work, the velocity and temperature fields are calculated u...

This paper is based on the numerical investigation of natural convection two vertical enclosure square and triangular cavity with air filled. The consist adiabatic hot cold wall wide range Rayleigh number from 103 to 106 aspect ratio 1 10 at interval 2.5. Flow patterns isotherm plots were used display results, for every case, local mean Nusselt values also produced. results show that an increas...

Numerical investigations are performed into the natural convection heat transfer characteristics within a wavy-wall enclosure filled with Cu-water nanofluid. In the paper, the bottom wall of the enclosure has a wavy geometry and is maintained at a constant high temperature, while the top wall is straight and is maintained at a constant low temperature. The left and right walls of the enclosure ...
