$layer = Mage::getSingleton(‘catalog/layer’);
$_category = $layer->getCurrentCategory();
$currentCategoryId= $_category->getId();
$children = Mage::getModel('catalog/category')->getCategories(currentCategoryId);
foreach ($children as $category) {
   echo '<h1>'. $category->getName().'</h1>'
   $collection = Mage::getModel('catalog/product')->getCollection()->addCategoryFilter($category);
   foreach($collection as $product)
   {
       $_product = Mage::getModel('catalog/product')->load($productID);
       /* Do What You Want With Products
   }
}
