Soil erosion is an important environmental phenomenon that causes many side effects such as reduction of soil productivity in the fields and transportation of pollutants to non-contaminated areas. Extensive well designed and controlled flume experiments in ...

Sediment transport in overland flow interacts dynamically with the soil surface morphology, which is often assumed to be static. This assumption, although it limits the predictive capacity of models, is reasonable since the morphological evolution is diffi ...

Temporally variable rainfall was applied on an initially dry, ploughed and smoothed agricultural soil to investigate the hysteresis pattern in the sediment concentration- discharge relation using laboratory flume experiments. The erosion flume had dimensio ...

We consider flow-through systems in which the characteristic length is limited such that turbulent flow is not reached even at high fluid velocities, i.e., the flow remains laminar. Inthese flow regimes, inducing circulation or vortices in the flow enhance ...

Heat-transfer enhancement in a uniformly heated slot mini-channel due to vortices shed from an adiabatic circular cylinder is numerically investigated. The effects of gap spacing between the cylinder and bottom wall on wall heat transfer and pressure drop ...

Heat convection from the uniformly heated walls of a straight channel in presence of a rotationally oscillating cylinder (ROC) is simulated at Re = 100. Heat transfer enhancement due to vortex shedding from the ROC is investigated. Systematic studies are p ...

Oscillating structures and actuators can induce flow kinematics that enhances mixing. This approach is specifically effective for mixing enhancement in meso-scale channels, where the flow kinematics can be actively controlled using micro-electro-mechanical ...
