Subject: [esp-r]  Question about water flowing between two glazing layers.

Hello, all.

I am doing investigation about water flowing between two layers of glazing. Is there any related module in ESP-r?

My problems are:

1,How to handle the convective heat transfer coefficient between the water and ambient glazing when the water is flowing at different speed?
2, The solar light will transmit the two layers of glazing and one layer of water inside in the daytime, of course. How to ascertain the solar absorptance and transmittance of the water layer?

Wow, amazing things that people are thinking about.  To discuss, this some further
description would be useful:

a) can you explain the context of this water flowing between glazing (what is this
    representing)?

b) where, specifically, is the water flowing from and to?

c) is it a part of an an environmental control system, or water at a fixed inlet temperature?

d) does it always flow in the same direction, at the same rate or every stop flowing?

e) how many times would this situation happen in your model - one time or 100 times?

f) what thermophysical information about the performance of the water and glass is
   of interest?

We might start from the idea that water flowing between two plates will be something
like a heat exchanger.
