hydraulic simulation of water flow in irrigation canals may reveal management shortcomings and help managers find solutions to them. hydraulic simulation models can be appropriate tools for understanding hydraulic behavior of irrigation systems. in the present study, the steady state hec-ras model was tested and compared with the mike 11 unsteady state model. a secondary irrigation canal in the...

Heat transfer operations in microchannel are of special relevance designing micro-devices involving accumulation high heat flux. The current study explores simultaneously developing, unsteady laminar flow inside a twisted sinusoidal wavy and involved. A square cross-sectioned channel is taken for the study. nature as well about axis. modified geometry helps enhancing out plane mixing fluid form...

This paper presents a numerical simulation of the developing flow and heat transfer of a viscoelastic fluid in a rectangular duct. In fully developed flow of a viscoelastic fluid in a non-circular duct, secondary flows normal to the flow direction are expected to enhance the rate of heat and mass transfer. On the other hand, properties such as viscosity, thermal conductivity, specific heat and ...
