The effects of geometrical parameters on thermalresistancebased on entransy dissipation caused by heat transfer (R ht) and fluidfriction(R ff) ofspiral-wound heat exchanger (SWHE) were studied by numerical method.The simulation results show that all geometrical parameters (spiralangle, external diameter, layer pitch, tube pitch) are negatively correlated with R ff because of flow pattern ...

Under the effect offriction resistance, the accelerated speed of raw materials when they sliding down along the jaw plates is smaller than the acceleration of gravity. And the jaw plates bear impact force and shearing force when the raw materials are fed into crushing cavity, which will also damage the jaw plates.
