Model for observing EZ characteristics in fluid and manufacturing method of model

The invention provides a model for observing EZ characteristics in a fluid and a manufacturing method of the model. The manufacturing method comprises the steps: after a hydrophilic colloidal materialis selected to be mixed with a solvent, heating and stirring are conducted, after a mixture is boiled, fire is turned off, stirring continues being conducted till the interface is smooth, and after cooling, a gel block is obtained; before the hydrophilic colloidal material is cooled and solidified, a plurality of inserts are added into the mixture; and after the colloidal material is cooled and solidified, the inserts are pulled out, and then the model provided with a plurality of hollow channels and used for observing the EZ characteristics in the fluid can be obtained. The selected hydrophilic material is wide in source and low in cost, thus in the machining process, the shape and size of the hydrophilic gel block are easy to control, and university of the model is improved advantageously; the requirements of a
