CWC and wind tunnel products

It is a CWC developed to respond to experiments using relatively fast flow.
It is an experimental CWC that can be decompressed for cavitation, which is one of the fluid phenomena.
It is a CWC which generates a flow by providing two impellers arranged in parallel at the bottom of the tank and rotating them in opposite directions.
We made for the purpose of conducting research on various flows in the coastal continental shelf area and research on wind waves.
In the oscillatory flow CWC, the flow direction of the observation part can be changed at any cycle.
It is an experimental device that can be handled easily and can be set in full scale.
It is a simplified personal tank developed to make the personal tank more affordable.
An elongated water channel suitable for two dimensionally elucidating phenomena.

The thermal stratification tank is an experimental device that can set several layers of water with different temparatures in the test section.

Accurately reproduce large-scale natural phenomena in the atmosphere.
We are reducing the noise of each device with a small size and low price.
It is a wind tunnel where you can experiment while keeping the measurement part in a quiet environment.

It can be operated continuously and has low noise.

This is to make the flow velocity distribution in the depth direction uniform in the observation section of the CWC.

Experimental equipment and measuring equipment

A device for measuring the resistance of a model ship in a CWC.
It is a device for conducting performance research and development of propellers.
It is a small and lightweight wave making device that can combine multiple sheets.
Developed for laboratory use to support research and development on micro bubbles.
It is a control device to move and set each sensor and test object to any position in X, Y, Z three-dimensional direction with high accuracy.
An impeller-type velocimeter capable of measuring the flow direction and flow velocity.
The remote control from land controls the propeller and rudder, and tests by manual and autopilot.
It is a system that measures the bubble size distribution in liquid using ultrasonic signals.
This device is used for self-propulsion tests and propeller-only tests of model ships.

Research and development and model

It is a tape corresponding to the barrier free.
It is a tape corresponding to the barrier free.
It is covered with a new ladder for elderly people.
It has a roof for the elderly and a solar power source.
Cavitation experiments can be performed by using an ultrasonic bubble nucleus measuring device and a bubble removing device in combination.
We make precise scale models and conduct high precision hydraulic experiments.
It is a system that makes numerical control data from offset and cuts model ship.
