Lotsa people don't understand what the fork means in reality. I'll try to explain it in a simplified way on this case.
On the 1st of August 2017 a new blockchain was created. It was created as a copy of existing one. So all BTC addresses to exist prior to fork, exist on both blockchains now. Meaning if you send your BCH to address created prior to fork, your BCH will be sent to address within BCH blockchain, as it is now completely separate blockchain from BTC.
If you try to send your BCH to BTC address created after the fork, it does nothing. It is the same situation if you would send the BTC to made up address. Such transaction cannot be confirmed by any node.
It is basically the same question if it is possible to send BTC to Litecoin address for example. Answer is no, it is NOT.

I think you will lose Bitcoincash that you sent to BTC address, there is no way to recover. Who will try it? 
I was wondering what if someone accidentally sends Bitcoin Cash to a Bitcoin address?
until today and possibly still in the near future both bitcoin and bitcoin cash are using the same keys. this means private key of bitcoin is the same as private key of bitcoin cash.
if you have a bitcoin cash address and send bitcoin to that address you can simply export that private key from your bitcoin cash wallet and import it in bitcoin wallet and have your funds.
if that address belongs to a service like an exchange you need to ask them to do it for you but they may not.
in the future bitcoin cash may change the keys to have a new address format in that case you will be unable to send anything to those addresses because if you put that in your bitcoin wallet it will reject it.
p.s. be careful when using bitcoin cash wallets they may not be as trusted as you may think.
. goodluck and be safe. 
Everyone here in the previous comments are clueless, bitcoin cash and bitcoin use the exact same private keys so if you sent bitcoin cash to a bitcoin address the owner of that bitcoin address can claim it on a bitcoin cash wallet by loading up their private key.
In other words you lose nothing.
What happens depends on whether or not the address was created before or after the split. In other words you lose nothing.
Why don't you just be diligent and make sure to sen to the right address? 
Serious though... this is a great question. No one so far has given a clear answer as to what will happen. I am very curious to know.

Yes absolutely we can,
BTC and BCH/BCC address are identically same,in other words they're living in the same roof.
even if you accidentally send it to your BTC address you still can claim it,
well another real history you can see it in here :

he did it,and you can see it how he handled it.
obviously,if you send it into third party wallets you need them to help you out.
PS : For now you can do it,but for tomorrow ? try to avoid this kind of mistakes not a good thing for you to do it obviously.
That's why bcash has problems regarding send and receive, it has some bugs and must be solved.
I have read a warning before send bcc into btc address which said your bitcoin will be lost.
Well, I don't know for sure because I have not tried it yet but considering bcash and bitcoin running on different chain, it should be impossible to send one to another chain.
I'm not sure for bugs but if the private key is the same then I think you should be able to claim it in the other chains wallet even if you accidentally send the wrong coin.
Anyway it can be confusing I think the best advice is double check your transaction before you send.

for now I think we cant yet transfer bitcoin cash, it is ongoing maintenance or something, we will just wait for a few days or a week for us to use or transact bitcoin cash.

Bitcoin and bitcoincash addresses are pretty much same so if you have bitcoin paper wallet or address & privatekey pairs than you can move both bitcoin and bitcoincash from it. So yes you can store both coins in the same bitcoin address if you have full control over that address but you might have to use different wallet to send them out like electrum for bitcoin and elecroncash for bitcoincash.

LOL..Receiver can somehow claim it..
on other word you lost it.
What he meant is that the transaction will go through and the coins are not lost in Nirvana. Of course, if you send coins to an address that you don't own, they are gone - no matter if it is a BTC or a BCH address.
I am a little bit confused about this. IMO, if I had BTC before August 1, then both the BTC address and the BCH address must be the same, right? Or do I need to create a separate address?

The person sending bch to btc address will surely lose it. Blockchain for both currency are didfferent and cant be mixed. The BCH sent to BTC address will be failed or lost. Perhaps while sending BCH it willprompt that the address is invalid but as the address for both are a bit similar there is a huge chamce to loose your BCH.

Lost it.
I think the transaction cant be done, it will failed because the bCh and the btc have a different blockchain. They look similar on address and key, but its still have a different place. So if u send a bch to a btc wallet, it cant be sign, and will fail I think.
